For me turning off accessibility settings fixed it, but that was some months ago.
I tried out the magnification button and reduced animations before that. Removing these settings resulted in no more crashes. I still use 3 button navigation though.
I think when reporting profile switch crashes, adding what accessibility settings are used might be helpful to narrow it down in the future.
Got some launcher crashes (which didn't crash the phone completely) a few weeks ago, but not last days anymore. But they seem reported by others already on GitHub. And were because of the new patches.
