Writing/editing IPTC metadata causes LR Classic to crash!

A quick search of ”metadata crashing” didn’t reveal anything, so here goes. I have been having ongoing issues w/ LR Classic tanking while editing input fields on a user preset (wire service IPTC) metadata setting. No apparent pattern (though apparently more likely the tighter the deadline/later the hour) I can discern, just a hang and crash. Sometimes I get a report window, sometimes not.

Anyone else facing this? Found a workaround? Adobe has been unresponsive to my pleas to get this fixed. It just tanked twice in five minutes. I’ve tried laptop restarts, etc. I’m using LR Classic 15.1.1 on a MBP M3 Pro chip and Sequoia 15.7.3.

Any and all help appreciated. This is a real PITA for a photojournalist on deadline, and often exhausted after long days trying to file. C’mon Adobe, don’t give us A.I. just keep what was working, working for photo professionals! My old disk version of LR did NOT do this.
