but that sounds more like an issue with your controllers or the settings. I assume you not needed to delete all your settings 
.
@Dargelis3433 .. you can remove ( or backup ) the input files first. Or the more safe way: try to clean the controller settings in game menu. Only if that will not help, you can try the “big hammer solution” and remove all online-files.
May be you can also backup some files before, the local cache folder and the link to Steam-Cloud is mentioned here:
The steps to delete all Steam files, you find here:

( so you can also try to partly remove files, e.g. only the input_xxx files first )
