After updating to macOS 15.1.1, everything stopped working.

1. microsoft outlook does not open.
2. cannot save files from any microsoft apps.
3. internet connection became extremely unstable, while other not-updated mac devices did not have this problems.

My device with lots of trouble is MacBook Pro with Intel Chip.

Anyone has resolved the issue? I waitied already many days, nothing improving or any other additional patched avaialble.
