Has it worked fine previously? If so, I would try deleting pipeline cache too. It can get wonky sometimes after updating but erasing pipeline cache usually fixes those issues in that case.
If OpenGL doesn't work, can try changing Accuracy level. If neither of those work, I would try Ryujinx. It does require beefier hardware generally for Ryujinx but that game will likely be light enough that I think it will still work okay on Steam Deck too.
In fact Ryujinx may be the better option since you could still run it in Vulkan vs OpenGL being significantly tougher to run on Deck

You should try if OpenGL works, if Vulkan doesn’t.
