Re open issue #5626

[jamercee]

I'd like to re-open #5626

Yesterday, I reported an issue I was having with openshot. The issue affected my Windows 11 Pro installation, suddenly generating BEX64 events and crashing on load. It appeared to be solved by updating the Intel Arc driver, but this morning the issue has reoccurred.

Over night, Windows did apply updates, but there do not appear to be anything related to video drivers.

I ran openshot with the gdb debugger, and I've included a capture below of the thread error. My quick read is this is something related to DirectX12. Would someone mind glancing this over and letting me know what they think?

Thanks

Do you by any chance have made any changes in OpenShot regarding Hardware Acceleration?

Please try this:

1. Close OpenShot if running.
2. Make a backup of c:\users\username.openshot_qt folder.
3. Delete c:\users\username.openshot_qt folder.
4. Start OpenShot and test.

Let us know the result.

First, thanks very much for taking the time to help.

I've made no changes regarding hardware acceleration & openshot. I do have Hardware-accelerated GPU Scheduling turned on at the system level, but I just turned it off, rebooted & retryed. Same crash sequence -- no change. To eliminate the possibility I made some sort of profile change somewhere, I just did a complete remove / reinstall from scratch of openshot, but no difference.

Regarding the openshot_qt folder, I routinely have been deleting that.

What's interesting is that when it crashes, it seems to be a point a point in the boot cycle that is before logs are created. When I delete the openshot_qt folder, the skeleton structure of folders get recreated, but the directories are all empty.

Thank you @jamercee for all that information. This is beyond my expertise. I just assigned this to the lead developer for his review and next steps.
