Hello @Gorkido, the uninstall process of Proton and checking if any games are configured to depend on a specific version Proton is managed by Steam, not Proton itself, so I've gone ahead and transferred this issue report to the Steam client issue tracker.

Thanks @kisak-valve
there needs to be a better tool which displays all the games that proton is configured to use
i have 400 games installed each with different versions of proton selected
alternatively delete the proton folder and dont allow it to update.

How am i supposed to not allow it to update?

Issue solved.
Fix: Start steam from a terminal and try to delete proton. You'll see some games just like this
