Hi Heisted, Welcome to the Forums.
As a quick check: Is your project in a OneDrive folder?
Or maybe in a folder that can change read/write permissions on files? (Just spitballing, I’m unsure if that’s a client side or server side lock.)
Does this happen with any other of your projects?
It looks like there was a recent change to URC, it may be helpful to share your urc logs.
