These are the entire logs. The command I used to start debugging was netcoredbg --interpreter=cli -- dotnet tModLoader.dll. All of the permissions for any files it would be looking at are set properly, and it doesn't even work with root so I'm not sure could be wrong. I can provide any additional information if needed

[viewizard]

Note, for CoreCLR native code 0x80070005 is not only E_ACCESSDENIED but also could be COR_E_UNAUTHORIZEDACCESS: https://github.com/dotnet/runtime/blob/ed41478a0b16210901eb9067730b2f91966fd1d2/src/coreclr/pal/prebuilt/inc/corerror.h#L405

I could not help you too much in this case, since you receive this error code directly from CoreCLR public API, not from debugger inself: https://github.com/dotnet/runtime/blob/ed41478a0b16210901eb9067730b2f91966fd1d2/src/coreclr/dlls/dbgshim/dbgshim.cpp#L81

Just note, you issue related to process start by CoreCLR, you could try:

• check, that dotnet tModLoader.dll work for you;
• try with absolute path for tModLoader.dll;
• with strace find out what open call have return error, or something like that.

[ppebb]

dotnet tModLoader.dll works fine, using the absolute path doesn't change anything. https://paste.ppeb.me/uqaqefelam.yaml here are the full strace logs though. I've read through them and can't really figure anything out.

[viewizard]

dotnet tModLoader.dll works fine, using the absolute path doesn't change anything.

Let me think, that by some reason, CreateProcessForLaunch can't fork/exec... https://docs.microsoft.com/en-us/dotnet/framework/unmanaged-api/debugging/createprocessforlaunch-function looks like Return Value section here is wrong.

https://paste.ppeb.me/uqaqefelam.yaml here are the full strace logs though. I've read through them and can't really figure anything out.

I can't open https://paste.ppeb.me/uqaqefelam.yaml, see only ERR_CONNECTION_TIMED_OUT.

Are you using SELinux/SMACK/AppArmor in your distro? Please, provide dmesg output right aftrer you have this error.

Not sure why the url didn't work but here it is. As for SELinux/SMACK/AppArmor, I can't think of why I'd have any of those since I'm just using arch and don't recall installing any of them (do note that netcoredbg works for other c# applications, this issue seems to be specific to this dll).

As for dmesg, nothing seems to be printing there related to the pid of netcoredbg. The pid of netcoredbg doesn't show there at all and the only messages there unrelated to boot are about usb devices.

[viewizard]

do note that netcoredbg works for other c# applications, this issue seems to be specific to this dll

Hmm, you didn't mentioned that you have issue with this dll only.

Another idea - CLI have specific work with terminal in order to work proper for all cases, just for test purposes try with MI/GDB: netcoredbg --interpreter=mi -- dotnet tModLoader.dll -exec-run - run -exec-continue - continue -gdb-exit - quit At least we will know, that your issue not related to CLI's manipulations with stdin/stdout/stderr.

[ppebb]

Running netcoredbg --interpreter=mi -- dotnet tModLoader.dll gives

-exec-run
^error,msg="Error: 0x80070005"

That's all it puts out.

[viewizard]

Could you please provide more info about your environment: CoreCLR runtime version (.Net SDK version), netcoredbg (did you downloaded it or built) - I need understand what CoreCLR version you have and what dbgshim (from what CoreCLR version you are using). Also, any chance you can attach to this issue your dll/json/pdb (no sources needed) that let me start it with dotnet?

I am at vacation till 11 May, but after that I could try to reproduce this issue at office (and I hope find out what is wrong and why dbgshim don't like this dll).

[ppebb]

My dotnet version is 6.0.102 My netcoredbg version is 2.0.0-58 (b3598e5, Release). I used the aur package so I believe it's built

The dll and pdb can be found here https://github.com/tModLoader/tModLoader/actions/runs/2288375060#artifacts=. The release build in the artifacts.

[ppebb]

For some reason, using the full path to dotnet worked just fine. Running netcoredbg --interpreter=cli -- /usr/bin/dotnet tModLoader.dll fixed it

[viewizard]

Hmm... are you have 2 dotnet in system? Could it use another dotnet by some reason?

[ppebb]

Oh no it's because there was a dotnet folder in the tModLoader folder. tModLoader's startup scripts install a new version of dotnet to a folder so that bug reports are all on the same dotnet version, deleting the folder fixes it.

[viewizard]

Solved issue - best issue. :-)
