Cura Master crashes on file->open Windows 10 on my machine

[andymozza]

Application Version Cura Master build from your dropbox. Tried with a few builds and latest I tried was Cura-mb-master-win64-20200610

Platform WIndows 10 1909 and now 2004

Printer Seems not related to chosen printer profile

Steps to Reproduce Go to File-> Open Files

Actual Results Cura just closes completely, no error or warning it just disappears from screen.

Expected results Cura 4.6.1 build from Ultimaker actually shows the file browser and chooses and lets me pick the stl file.

Additional Information I have tested the current build from Ultimaker and this does not show the same issue. I have cleaned out the Master install location and re-installed fresh to ensure there are no left overs.

Hi, if this is something its possible to investigate, then what files / logs should I attach - please let me know. Are there differences between runtimes / libraries used in your build that might affect this ? Appreciate any thoughts on where to go next with diagnosing.

Hmm, don't know what is happening there but there could be something useful in the log files which will be under AppData, can you find the cura.log and stderr.log files and zip up and attach to this issue, thanks.

[smartavionics]

I don't know anything about Windows as I only use it for building Cura releases! How do you find out the OS version?

[andymozza]

cura.log

stderr.log

I found these in Appdata->Roaming->Cura->master, but there is nothing recorded about the exit when I open the file browser. Last thing is simply the error because it can't upload the backup.

[andymozza]

Also notice that I have this folder somehow and it has crash dumps in it . There is one for cura at the time it crashed.

[andymozza]

Cura.exe.38508.dmp.zip

Not sure if this is of any use. I don't know how to read / view it...... edit - google tells me there is an app in the Microsoft store in preview state to read these .dmp file: https://www.microsoft.com/en-gb/p/windbg-preview/9pgjgd53tn86?rtc=1&activetab=pivot:overviewtab

[smartavionics]

I just tried my latest build and it doesn't crash. The Windows version is Windows 10 home 1903.

Here is the full output of the rather impressive new dmp tool from Microsoft... it actually goes and grabs all the dlls,symbols etc automatically.... Not sure if this means anything to you:

Please search your machine for QtCore.dll and see if you have other instances of that which may conflict with what is supplied in my release.

[andymozza]

I have 'loads' of other instances of the file on the machine, but I don't think any should override yours as they are not in the path. I do notice yours is a newer version that the one in 4.6.1

[andymozza]

Ok!! Your hint for the qt dll and the mention of chitubox in the stack trace sent me off googling.

I found references to dell backup manager causing later qt to crash in other applications as it installed a file filter which did something inside the file manager.

Chitibox( sla/resin slicer) now includes a file preview thumbnail generator when you view files in windows file explorer...... Chitubox also had a qt5core dll in the list. Chitubox was also in the stack trace for opening the file filter ( obviously it’s loaded when you open a file dialogue to browse and choose inside cura).

So - I unregistered the dll that chitubox supply for creating the preview of the thumbnail and thus resolved it.

Older cura QT version didn’t appear to have a problem with it.

As always thanks for pointing me in the right direction!

[smartavionics]

As always thanks for pointing me in the right direction!

It was a lucky guess, glad you found a solution, closing...

How did you do this specifically?

[andymozza]

There seems to be a post in the chitibox forum now.

https://forum.chitubox.com/?thread-419.htm

I did the regsvr32 /u dll-path option and restarted.

[dryphi]

I just uninstalled ChituBox. Cura works fine now.
