dbl219 already invented workaround - write the name of a preset with extension and press OK, and don't press search "(...)" button.
But I think his problem is a bit different, though
whitestar below had the same, so there are more of us:
reshade.me/forum/troubleshooting/6268-ca...reset-in-4-5-4#37887
I have a crash on installing newest Reshade when I press (...) to pick default preset. Just it.
I performed some tests and
Reshade 4.5.3
is free from the issue.
Game picked to install doesn't matter.
I also checked when the game path was without any spaces, no diacritic marks, when the game had already installed Reshade, and as performing update, and also when it was fresh installation, as DX9, DX10/11/12. No success.
In the very beginning of using 4.5.4 I only picked all shaders, and since then they are picked all the time, so I can't test whether it has any influence on this bug.
I afraid that lot of people might have this bug so the fix will be highly awaited.
