Issue with saving file with v22.1 after bringing in exported .gmp file containing DEMs.


I have hit a bit of a snag trying to save a .gmw file after we exported a number of DEM layers to a .gmp file, and then brought those back in to the .gmw file, in an effort to reduce .gmw file size (it was nearing 18GB). 
The particulars are:
Version: Global Mapper v22.1.0 (b021721) (73) [64-bit] - REGISTERED
Error MSG: 

Saving workspace <C:\Users\nickv\AppData\Local\Temp\GlobalMapper\TMP21828\GMW1F6F.tmp.gmw> - Writing Layer Year 1 Pit_V2

An incorrect file handle was associated with C:\Users\nickv\AppData\Local\Temp\GlobalMapper\TMP21828\GMW1F6F.tmp.gmw.

I have managed to save the file using: Global Mapper v21.1.1 (b081620) (271) [64-bit] - REGISTERED 
but not with the current build.
