It just happened to me, too.
Turned on xbox and all local saves are gone. I thought it would be ok because every save is sent to Larian servers, but for some reason the last save available to me is dated Jan 27th.
Lost about 30 hours of progress, which I definitely don't want to replay.
Just lost all interest in continuing the compaign.
Both Xbox and BG3 are up to date.
WTF
