OBS craches on startup

[fixertm]

Hi,
Been searching posts and similar issues to mine for 2 days now and it seems I can't seem to find a fix.
OBS keeps crashing when i try to start it, either in safe mode or when started normally.
Not sure why it says in the log i'm using Windows 10, i'm using Windows 11 Pro.

Attaching the last logs.
Did troubleshooting steps like
- windows firewall
- allowed everything
- updated all my drivers
It's not from streamfx.
I did not reinstall, as I don't want to lose my settings i've made, because i'm not sure I remember how to do them again :D
Thx again for your help.

This is crash during creation of the shader cache for OBS internal needs. The error: "Unhandled exception: e06d7363" is strange. I think, that the "libobs-d3d11.dll!std::filesystem::_Throw_fs_error" call and the mentioned error says that the given path for the shader cache is not accessible. It can be wrong symbol (from Unicode set) in the file path or something else. The shader cache is located in: Edit %APPDATA%\obs-studio\shader-cache %ProgramData%\obs-studio\shader-cache try to remove this folder manually (it will be recreated on next OBS startup).

pretty strange stuff happening.
I remember I tried deleting it before but it gave some kind of error, and it was the only file I had.
I installed newest OBS version and now i'm trying to navigate to the path and shader-cache folder is not present.
I attached new crash report

If the folder is not present that's a bad sign - it means OBS can't write to your AppData folder. Check your filesystem permissions allow this. Also, does your username contain any unicode or other special characters?

 

[fixertm]

It seems that all permissions are allowed for obs
I don't have a wierd name.

Do you know how to run OBS portable mode from different folder?

 

[fixertm]

I just learned from the internet.
Used these sources :

Running in Portable Mode | OBS

OBS (Open Broadcaster Software) is free and open source software for video recording and live streaming. Stream to Twitch, YouTube and many other providers or record your own videos with high quality H264 / AAC encoding.

obsproject.com

Launch Parameters | OBS

obsproject.com

and a random youtube: https://www.youtube.com/watch?v=K7WqZ9848U8&ab_channel=MachineDaena
Followed them but it still crashed.
I tried reinstalling it now again and re-tested, same result.

Attaching logs again, one when i clicked "run in safe mode" one with "run normally", but they look the same to me

 

[Suslik V]

Can you provide the crash log from the OBS "config" folder inside the portable installation that you have placed in a simple, recently created folder, like "C:\OBS"?

 

[Suslik V]

In other words, to make OBS portable in a new folder (please read after the words "if it was not clear"): https://obsproject.com/forum/thread...»-when-opening-app-settings.82157/post-346499

 

[fixertm]

Big thanks for still helping me out!!!
I've saved your link for future use as well, very helpful!

So, I did the steps. I downloaded OBS-Studio-31.1.2-Windows-x64.zip , created the new folder, created portable_mode. Everything as instructed, step-by-step.
I got a new error message when doing step 5 "Now open file explorer and run the C:\OBS\bin\64bit\obs64.exe" (see "obs" screenshot)
I then checked and folder "config" did appear. I also ran a search inside the C:/OBS folder and I do have "locale" file.
I then tried to manually go into bin-> to run obs64.exe and it crashed again. I uploaded the new crash text.

I'm at a loss of words, have no idea why this is happening when it worked before, I streamed on twitch and everything was fine.
Is there anything else I can test?

 

[Suslik V]

You cannot run "C:\OBS\bin\64bit\obs64.exe" from command line until current directory changed ("cd" command with path to the executable folder needed before launch). Thus there was "locale" error.

As for the portable - can you try to run OBS from USB stick drive or SD card? (These drives usually formatted FAT or exFAT without access rights management)

 

[fixertm]

Ok thanks, I'll try it this week

 

[R1CH]

Actually the shader cache is in %programdata%\obs-studio\shader-cache - check you can write there with a standard user account.
