The Logi Options+ mouse driver regularly either fails to launch or crashes and doesn't re-launch when switching between two user accounts. This has been a chronic problem for YEARS even with non-beta versions; the entire reason I'm using the beta is the hope that it will be less common.

In the past it was possible to force-quit the Logi process to get it to re-spawn, but as of Logi Options+ 0.91 the backend appears to fail to launch entirely (the settings app reports a backend failure, and there don't appear to be any Logi processes for this user in Activity Monitor).

System is a fully up-to-date Monterey install, 2020 iMac, although variations of this problem have existed through multiple OS and Logitech MX Master 2 and 3 driver versions.
