I'm getting an error message on startup: An errror occurred importing addon PropSwap : ERROR: bad magic number in 'PropSwap': b'x03xf3rn'

No idea what it means.

You have some kind of auto-start Python script in one of your runtimes. The "bad magic number" means that it does not work with the actual Python version.
