Can't partition half my drive

Hello. I am trying to install Windows on a partition. My HDD was already partitioned into two aprox equal sized partitions.

The pictures are from my Mac and in Danish. I recon you can recognise the functions as they are placed in the same place in all languages. :-)

I can select to enlarge the Mac partition, but it fails to be partitioned.

It states my drive is damaged, but I can't successfully repair it even though the firsthelp or disrepair function states it was successful.

After trying to get Boot Camp Assistant to install to the free space, the space suddenly locked up, and now I can't do anything to it. I tried to use Disk Utility firsthelp but no change.

How do I unlock such space?

MacBook Pro 16″, macOS 12.1

If you are trying to recover space after BootCamp— you can erase/reformat/initialize the parent drive as new—then restore your user data from a backup.

You can add Volumes without penalty to the Container without partitioning

Add, delete, or erase APFS volumes in Disk Utility on Mac

For Bootcamp on supported machines—

Install Windows 10 on your Mac with Boot Camp Assistant

Firstly - one should always leave the Partitioning of the Drive to Boot Camp as well as leaving it to Bootcamp to if or when you what to remove an installation of MS Windows 10.
