Boot Camp stuck on 'partitioning disk'

I'm trying to use Boot Camp Assistant to install Windows 10 on my IMAC (Catalina). It keeps getting stuck at partitioning disk (not unresponsive, just not progressing). Any solution please?

iMac 21.5", macOS 10.15

Post a screen shot for the second command, or use PasteBin.com.

This GPT2 is not correct.

Ok so when writing that in terminal, everything was ok with disc.



Trying to partition, gives me an error: 'could not be partitioned'. 'An error occurred while partitioning the disk. Please run First Aid from within Disk Utility to check and fix the error.'


Checked on apple website https://support.apple.com/en-us/HT209102


I ran disk utility, still error.


I do have free space as they say but I can't remove it like they suggest... it's saying 'The target disk is too small for this operation, possibly due to partition map limits. : (-69519)'



Any ideas? THANKS!!
