I did follow your directions, and this morning, a mere 18 days later, it happened again. All of my carefully placed favorites are gone from my sidebar. I wish I understood why this keeps happening. Does a plist get corrupted that often or that quickly that I keep having to deal with this?
No, something is not right. I have never encountered your re-occurring issue.
To trouble shoot further you can:
—A SafeBoot Use safe mode on your Mac - Apple Support will sort many anomalies
Does a quick disk repair before it fully boots up, and certain system caches get cleared and rebuilt, third party system modifications and system accelerations are disabled.
Login and test. Reboot as normal and test. Caches get rebuilt automatically.
This test will tell you if third party interference; most extensions etc are not loaded in safe boot mode.
—Test issue in another user (or guest user) account Change Users & Groups settings on Mac - Apple Support
This will tell you if it a universal issue or isolated to your user/admin account.
unplug all non-essential peripherals when testing
Uninstall all third party apps that are Cleaners/Optimizers/VPN/Anti-Virus
all known to cause issues on the macOS
