I might like so as to add a 30GB exFat partition as a shared space accessible from each home windows and macOS. Utilizing the bootcamp utility the disks presently seems to be like this:

/dev/disk0 (inside, bodily):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *500.3 GB   disk0
   1:                        EFI ⁨EFI⁩                     314.6 MB   disk0s1
   2:                 Apple_APFS ⁨Container disk1⁩         361.0 GB   disk0s2
                    (free house)                         10.0 GB    -
   3:       Microsoft Fundamental Knowledge ⁨BOOTCAMP⁩                129.0 GB   disk0s3

/dev/disk1 (synthesized):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      APFS Container Scheme -                      +361.0 GB   disk1
                                 Bodily Retailer disk0s2
   1:                APFS Quantity ⁨Macintosh HD - Knowledge⁩     245.5 GB   disk1s1
   2:                APFS Quantity ⁨Preboot⁩                 431.1 MB   disk1s2
   3:                APFS Quantity ⁨Restoration⁩                1.1 GB     disk1s3
   4:                APFS Quantity ⁨VM⁩                      1.1 GB     disk1s4
   5:                APFS Quantity ⁨Macintosh HD⁩            15.4 GB    disk1s5
   6:              APFS Snapshot ⁨com.apple.os.update-...⁩ 15.4 GB    disk1s5s1

I’ve tried to resize disk0s2 like this:

diskutil apfs resizecontainer disk0s2 300G ExFat SharedSwap1 0

And obtain the error:

Aligning shrink delta to 60,999,999,488 bytes and focusing on a brand new bodily retailer measurement of 299,999,997,952 bytes
Decided the minimal measurement for the focused bodily retailer of this APFS Container to be 360,999,997,440 bytes
Error: -69521: Your APFS Container resize request is beneath the APFS-system-imposed minimal container measurement (maybe attributable to APFS Snapshot utilization by Time Machine)

Upon checking snapshots:

diskutil ap listSnapshots /Volumes/Macintosh HD              
Snapshot for disk1s5s1 (1 discovered)

    Purgeable:   No
    NOTE:        This snapshot limits the minimal measurement of APFS Container disk1

Is it potential to resize and allocate extra space, or ought to I simply format and reinstall each working methods once more? If the latter is there a advisable course of for my finish results of Mac partition, Home windows and shared exFat house?
