Hello,
Errors from 2022-01-07 display that you have the memory problem and it was not resolved https://prnt.sc/26cquia
I would recommend you to check the list of active plugins and disable those that you don’t really need or use because every additional plugin uses PHP memory. Also, maybe ask your hosting provider which requests uses your PHP memory most of all to find out what could be the reason of such high memory usage.
Regards
