Mac partition is not present in boot after installing bootcamp

I have tried to extend the bootcamp drive with EaseUS software and now my Mac doesn't see the Mac Partition, only Windows (which is now called not Bootcamp, but Windows). Please assist me how to repair the boot sector? The Disk Utility does not see the Mac partition at all, it thinks that it is unmapped space.

You should never use any third party utilities to manipulate the partitions. You should only ever use the tools provided by the primary OS. An OS can have some odd undocumented quirks which third party utilities are not aware of. Plus resizing & moving partitions can change the location of bootloaders.


Boot into Recovery Mode or Internet Recovery Mode or from a bootable macOS USB installer and erase the whole physical drive before reinstalling macOS or restoring from a backup.
