Any ideas? Thank you.
Uninstall all third party apps that are Cleaners/Optimizers/VPN/Anti-Virus
all known to cause issues on the macOS
To trouble shoot further you can:
—Test issue in another user (or guest user) account Set up users, guests, and groups on Mac - Apple Support
This will tell you if it a universal issue or isolated to your user/admin account.
—SafeBoot How to use safe mode on your Mac - Apple Support will sort many anomalies
Takes a bit longer to get to the login screen, does a quick disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, font cache, etc.
Login and test. Reboot as normal and test. Caches get rebuilt automatically.
In Safe mode third party system modifications and system accelerations are disabled, it removes malware, etc impacting the smooth operation, however a reboot will put it back to normal mode.
This test will tell you if third party interference; extensions etc are not loaded in safe boot mode.
Plugging into an external keyboard and compariing your results would be telling...
