Games don't start, dlls missing?

This seems to be the case after the latest update.

And many more. Please help.

Try to use "Verify integrity of tool files..." under the "Local Files" section of the Properties of Proton 7.0 (accessible by right click on it) and "Verify integrity of tool files..." of the game.

Thanks for your answer. I did this for some of the tools listed including Proton 7 but it is still not working.

[turbo]

I did a factory reset and downloaded 400 GB Games again. Now it works but the solution is not very sustainable.

[Feychel]

sometimes proton experimental works (30% Of the time it works all the time lol)

[turbo]

Before the update everything was working normally. Somehow the important DLLs got lost. I think it has something todo with vc redist which was not installed correctly. After the reset the games installed vc redist and directx successfully.
