Trying to open a drawing (or any drawing) I was working on yesterday and locks up fusion when trying. This occured after updating this morning

Did you try restarting Fusion. Drawings open fine for me.

I had an issue this morning too.    What i was experiencing was the program not opening.  I right clicked on the Fusion screen that was trying to open and a new window opened , it gave me an option to repair fusion.   i checked the repair button, press ok and reopened fusion and it was all set to go.   I dont think this really addresses your problem but maybe it will.
