Not all games seem to be affected, Heroes of the Storm loads just fine

Thanks for taking a look at it! :D

[doitsujin]

Looks like there's an invalid shader somewhere. Please run the game with DXVK_SHADER_DUMP_PATH=/some/path set (note that you must create /some/path before), and upload that directory somewhere.

[Xaenalt]

One moment :D

[Xaenalt]

Bigger than the 10M limit, let me know if you can access this: https://drive.google.com/file/d/1SoiuE8Mp5OulTZDwQAOxBdoi6LlSE1fj/view?usp=sharing

[doitsujin]

Yeah that works, thanks. Will take a look.

[Xaenalt]

Awesome! Thanks so much! :D

[Xaenalt]

Was able to get back into the game by setting DXVK_STATE_CACHE=0, weird

[Xaenalt]

Unsetting it has the crash reoccur though

[doitsujin]

Should be fixed as of 0d049f105c5880794de8aa90100ed057878c0e88 6d814b24da9c0f4aba7d93e0825023364969a021, please test. Tell me if you need a build.

[Xaenalt]

If you could send me a build, that would be amazing, I have trouble compiling it on F28 due to too old mingw. I suppose I could compile the new mingw

[doitsujin]

Alright: dxvk-mhw-fix.tar.gz

[Xaenalt]

That does indeed seem to have fixed it :D thanks!
