2 - Then notice the infamous " CleanMyMac " aka BrickMyMac is the Notification Centre
Any Third Party Applications that will interfere with the normal operation of the OS, is an invitation for disaster and comprise the Operating System
Certain Applications maybe available on the Apple Apps Store - this only means the Developer is prepared to pay Apple a portion on each sale. What the Application may do to the computer is up to the User to check this out before purchase
Any of the below should be removed as per Developers Instructions
This will include CleanMyMac
Read some of the posting and arrive at your own conclusions.
Specific to CMM, MacKeeper and Dr Cleaner Pro Plus
Some Contributors suggest restarting in Recovery Mode and choosing to Reinstall the Operating System over the existing installation after the BrickMyMac has been Un-Installed via the Developers Instructions
This may or may not replace elements of the Entire Operating System including the Home Folder ( User Account ) and replace any corrupted or removed elements of the Operating System and make thing right.
Then there are Other Contributors ( like myself ) would suggest from this link Use Disk Utility to erase a Mac with Apple silicon.
Thereafter to start from scratch and install all Required Application directly from the Apple Apps Store or Directly from the Developer.
If going this route - I suggest Not using Startup Assist to migrate things back as this will probably Re-Introduce the existing issue that existed when the TM Backup was made
