Did you completely delete your PR folder before reinstalling? When you uninstall, all the custom stuff remains, so you would have to manually delete them.
Check your main PR folder, if I remember correctly, the reshade files for PR should be there if you installed them at some point (Don't have PR installed so can't check). If you didn't install reshade, then it's something else causing the crash.
I don't know exactly if reshade overwrites anything when installed, but you could try downloading the reshade files from here and then use it as a reference and delete whatever files come with it from your PR folder and see if that works. Again I can't guarantee that it doesn't mess up your game even more.
