Mistake deleting Bootcamp, BootCamp now lost partition

Hi there

I wanted to resize my Macintosh partition and forgot that I need to delete Windows by Bootcamp. Instead, I just removed it in Disk Utility. Windows are now gone, but I cannot reclaim the 100G that were allocated to Bootcamp.

What is also weird is that I cannot see those 100G in diskutil . (the file Vault is turned off )

i'm also finding this the teared which is not worked for me : https://discussions.apple.com/thread/8453248?answerId=33603637022#33603637022

/dev/disk0 (internal, physical):

   #:                       TYPE NAME                    SIZE       IDENTIFIER

   0:      GUID_partition_scheme                        *500.1 GB   disk0

                                 Unencrypted

I tried the above also in the recovery mode and it showed a number .In the disk utility I see the missing 100G as "free space" but cannot remove it . I just get an error. Any ideas?

Thanks
