Well after much in the way of what I would consider to be preliminary testing, it seems the workaround for 7.3.2.2 seems to be to simply to restart in Safe Mode, and be sure to choose “Reset to factory settings”. The checkboxes underneath may or may not also help. But this is the best I’ve got right now for something that may or may not make LO usable again.
And besides obviously not being something that users should be expected to do, I’m not sure the long-term effects of relying on such a workaround, but until a fix can be found, I am just going to have to use it. And use it I will, because I use LO at least weekly.
Even still, beach balls do show up from time to time. For example just now, as I opened a document, did my Descriptive Statistics thingie, and ⌘Q’ed, I got a beach ball and had to Force Quit. And earlier, I tried to maximize the window and once again got the bottom-right corner to expand followed by a beach ball (no top-left).
Furthermore, even after deleting my user profile (which really is the whole point of trying safe mode), beach balls are just everywhere, even with Full Disk Access enabled. This is clearly a bug and not just profile corruption.
Anyway, it sounds like my work’s cut out for me. Hopefully I can get to the bottom of this soon.
