Verify The current stable release of Monterey including bug fixes, is macOS 12.4

Keep your Mac up to date - Apple Support

You can try holding the Shift key and launch the Mail.app and compare your results...

if no insight or resolve try a rebooting the machine into SafeBoot Mode and test

—SafeBoot How to use safe mode on your Mac - Apple Support

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, 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 hampering 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.

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. 

Uninstall all third party apps that are Cleaners/Optimizers/VPN/Anti-Virus

all known to cause issues on the macOS
