System.TimeoutException: Waiting for ExecutionCompleted timed out

I’m having the same issue with multiple automations. It started happening after upgrading to Studio 2024.10.8.

This makes me doubt that it’s an install issue or an issue our automation(s). Sounds like a bug in Studio. I wouldn’t go messing with your system and doing reinstalls etc. because that could cause more problems. Don’t fix what isn’t broken. Hopefully UiPath acknowledges this and fixes it (or already has) in a future version.
