Can't mount Boot Camp partition on Mac after extending

My Mac has two partitions, one 200GB allocated for Boot Camp and the rest for macOS. I decided to shrink the Mac OS Extended partition to extend the Windows partition because it's almost full. To do this, I erased free space on the Mac partition and used MiniTool to perform the extension. The process was successful, and I can boot into both OSes without issues. However, Parallels no longer recognizes the Boot Camp partition, and Disk Utility won't mount it. I installed Tuxera NTFS to mount it but it failed with "Tuxera NTFS couldn't not mount /dev/disk3s3 at /Volumes/BootCamp." How can I fix this? P.S. Disk Utility also don't show the acurate size of the extended Boot Camp partition, although Windows Disk Management and MIniTool do.

If the Boot Camp partition doesn't mount in Tuxera NTFS, you can use a different NTFS tool instead. iBoysoft NTFS for Mac is an excellent alternative. You can download it from the button below to mount your Boot Camp partition. It also allows you to check and repair errors on the Windows partition.

If the partition still won't mount, the resizing process has likely caused issues with your partition scheme. Try using GDisk's expert menu to delete the GPT. Or, back up your data, erase your drive, and reinstall the OS.
