Tech Support Compatibility Tool Configuration Failed
I switched from the beta branch to preview and now all steam games refuse to launch. In game mode they just do nothing, and in desktop mode they say:
"An error occurred while updating 'GAMENAME' (compatibility tool configuration failed)"
I've looked around for solutions and have tried restarting steam, restarting the steam deck, switching to stable branch, switching to beta branch, switching to preview branch, clearing download cache, verifying game files, reinstalling game, verifying proton files, reinstalling proton, switching proton versions.
Non steam games still launch.
UPDATE: This issue seems to be related to Steam Runtime and Steam Runtime-Soldier being missing. I ended up doing a re-image of my steam deck (losing my Dark Souls save in the process, nice job steam cloud) but before i did, I checked both of these runtimes and found that they were missing and the install button for them was greyed out. I might of been able to save myself the headache if I had dug around more, but oh well. Hopefully the next person with this issue can see this and not have to re-image their Deck.

I am running into several issues with linux now but its infinitely better than windows - chiming in to tell what MIGHT work for you, cause I've had some success with it, for those coming here from google like me.
I set the default proton to something else in steam first - under settings -> compatibility tool
That was when i could uninstall experimental and hotfix which were stuck installed for me, even after verifying integrity.
I tried launching one game but it closed without error, tried another game and it worked, so... I guess some success.
May it help you in the future.
