I've tried this already but I just went ahead and unlocked it fully again. I'll see whats up when I get home from work in 8-9 hours.

Follow up: After 12 hours of the wallet being fully unlocked it has not frozen or given me the Unable to send beacon! message. This is the longest the wallet has ran fine since 3.6.x.x for me. I suppose I can just leave it fully unlocked?

no, just leave it unlocked with "for staking only" now
