it crashes and closes without a message of any kind

Not according to your log:

qBittorrent termination initiated qBittorrent is now ready to exit

[UsmanTariq2]

Yeah there are multiple log files . Dont know which one of them has the crash information. Here all multiple logs.zip

If they not there then crash info is not in log file since this is 1 day of logs

[thalieht]

Yeah i don't think a crash would appear in logs. Anyway if it's a crash and you want to help https://github.com/qbittorrent/qBittorrent/issues/5785#issuecomment-250839116 FYI without steps to reproduce or a stacktrace there is nothing we can do to find the problem so we may as well close the issue if you don't want to do what's in the link.

@UsmanTariq2 If there really is a crash happening, which could be a silent CTD (Crash To Desktop) scenario - there should be some *.dmp files in %LOCALAPPDATA%\CrashDumps or %userprofile%\AppData\Roaming\qBittorrent or there should be some information/error report under Windows Logs->Application of eventvwr

If there are *.dmp files, could you please provide them.

Examples:

---

[UsmanTariq2]

I did not find a *.dmp file at either location

I did find the crash event in Event viewer crash.zip

shows a 0XC0000409 exception...

@UsmanTariq2 In your logs, there are a large quantity of part file read alerts for a multitude of torrents.....have they been removed from your D:\ by any chance?

[UsmanTariq2]

U mean basically missing torrent files on local disk?

[UsmanTariq2]

The answer is on drive D i have been downloading a single torrent in parts, selective files, then deleting them as i dont need them anymore and then downloading other parts of the torrent . So yes I do have 1 torrent like that

Some of the files are occupying the disk space but not downloaded. I have deleted those. They were probably created because i accidently clicked on the whole folder Hope that helps

Ahh....another user reported something similar to this previously I believe.

[UsmanTariq2]

Link me to it, mabye i can corroborate

[xavier2k6]

Link me to it, mabye i can corroborate

It may or may not be same/similar to this #20362

Can you also run sfc /scannow in an elevated command prompt to ensure no corrupt OS files.

BTW what version & build of Windows 11 is this on?

[UsmanTariq2]

Ok it crashed again, same steps 1- Uncheck multiple files from a torrent inside qbittorent 2- Delete SOME of those files from your harddisk ( leave some there). Now there is a mismatch of files in hdd and in qbttorrent 3- Minimize the qbittorent and let it seed for a while ( 30 mins for me) 4- Upon maximizing briefly gets stuck and crashes without any message.

Other logs provided above. Hope thats enough for replication

@UsmanTariq2 Please update to qBittorrent 4.6.5.

If you still experience this issue/can reliably reproduce with that version & are willing to apply a debugger with defined rules, please let me know as I can't repro with current steps.

[UsmanTariq2]

i upgraded to 4.6.5, let me check if that still happens. WIll report back .Yes i would be willing to do apply a debugger

[UsmanTariq2]

Hello, Please tell me how do i apply the debugger so i can provide you with the information

[xavier2k6]

I presume that it's still happening with 4.6.5?? as you were going to update/feedback.

[UsmanTariq2]

yes it is still present

[xavier2k6]

yes it is still present

Ok, I'll come back to you over the weekend.

[UsmanTariq2]

Link the instructions for the debugger, i can follow them. Otherwise im waiting

[xavier2k6]

To aid us in any silent CTD (Crash To Desktop) scenario on Windows OS, where no user presented Crash Report is provided.

Close any instance of qBittorrent!

Please download & install Debug Diagnostic Tool

Download & extract these predefined rules -> DebugDiag_Rules_14.Jun.24.zip to your desktop or where you would like to.

Run DebugDiag 2 Collection from your start menu. (There may be a COM+ dialog pop-up) On the bottom right of the main window, you will find an Import button. Click the Import button & point it to where you extracted the rules above. DebugDiag_Rules_14.Jun.24.ddconfig The debugger rules should show active. You may now start qBittorrent As soon as there's a crash while running qBittorrent - it will capture a "stacktrace"

This will hopefully help point us in the right direction to where there's a problem in the program.

Please provide any qBittorrent related logs from C:\Program Files\DebugDiag\Logs (This should contain stack traces we need)

NOTE:

Your memory usage will probably increase more so than normal & the program itself may become unresponsive for a period of time or lag in certain user interactions due to having a debugger attached.

As soon as a crash occurs/stacktrace is created, it will be ok to "deactivate rules" & exit the debugger.

Also, qbitorrent is consuming considerable cpu resources and getting my device heated up, whilst bittorent(recent switcher) didnt consume or heat up my device as much. Might be worth looking into as well

[UsmanTariq2]

WIll get on this in a day or 2

[xavier2k6]

@UsmanTariq2 Any further crashes??

[UsmanTariq2]

DIdnt test it unfortunately. Will get on it

[xavier2k6]

@UsmanTariq2 Can you also grab/install latest Microsoft Visual C++ Redistributable. Latest Microsoft Visual C++ Redistributable Version

[UsmanTariq2]

will do
