trailing loader space error with disk0

looks like that did the trick, thanks very much LonerT !

well, i have Paragon HDM for mac, and in the past found i didn't have an issue using it.

what i was seeing was some very small amount of free space between my share and windows (about 100-200 mb), so i decided to do a little partition editing in HDM. removed share, then recreated it using all the free space, and placed it to the right of the windows partition (as you see below). it used to be between the APFS volume and Windows.

my mistake may have been that i did this with SIP enabled.

regarding doing a repairDisk, i hesitated because it was telling me it's going to wipe out the EFI partition.

Thanks for coming in to help with this ...

will give this a try later when i have access to my computer .... hopefully will resolve the issue.

i used to have a hybrid mbr setup, but since have wiped the entire ssd and redid everything while trying to resolve random freezing ....

share is not a critical partition, not a startup volume either. i do have a backup of it, yes ....
