Re-installing the app does not wipe the `%APPDATA%\itch\bin` folder though.
This is really frustrating because I would like to see exactly what's going on, but I can't because I can't reproduce the same issue on any of my windows installs :(
Here's what I would try out:
- Open a Command-Line prompt (`cmd.exe` in the start menu)
- cd to %APPDATA%\itch\bin
- execute `butler -V`
- execute `echo %ERRORLEVEL%`
- Download an older version of butler, https://dl.itch.ovh/butler/windows-amd64/v9.0.0/butler.exe for example, and do the same thing
- Run Process Monitor, filtered to "butler.exe", and do the same thing
Screenshots of the above would be super useful.
