Luban 4.10.1 Not saving

After using Luban 4.10.1, working with a new 10W laser upgrade (brilliant), have now found that Luban has stopped responding, after altering the dimensions of some svg items on the design Luban is now not letting me alter text, and now I find I cannot save anything so have just lost 2 hours work :face_with_symbols_over_mouth:
have tried every save button and nothing won’t let me exit without saying exit without save??? mad, need this bug fixed

Could you attach a screenshot or use some like screentogif to record what’s happening?

Same problem here. Cannot save to disk or stick
