Not sure what happened, but somehow GOG broke the REDprelauncher for Cyberpunk 2077...yes I've done the usual troubleshooting...at this point the only thing that fixes it, is uninstalling redlauncher (just that) and then despite that, the executable stays in Cyberpunk game folder, launch it, works, but that's a one-time deal. Have to uninstall again, etc, to make it work once you've quit.

Had the same issue, with the same temporary fix, but now Redlauncher stays uninstalled and prelauncher just directly opens the game
