Bambu knows about the issue as it is wide spread and are working on a fix.
If you need to print in the meantime disconnecting from Wifi seems like the best way to go.
Try it on a small print as a test, but using the steps I mentioned I have gone from every print failing completely to having no failures with my last 3 prints.
Submitting a ticket with the info they’ve asked for is the only other thing to do with this one until a fix comes out.
