Maximum exe size? application can't run on your PC

Our interior design firm has been sharing updates with an architect we partner with via .exe files in enscape and dwg exports from sketchup, and all has been going swimmingly until my last update to this home. File is fairly detailed (900MB SU file) the resulting enscape .exe is 1.91GB. I was able to open/run the exe files at 1.73GB output. Did I reach the end of the line for enscape executables?

Happy to share my SU file, or executable if needed.

Enscape version 3.5 14+99672 - tested output of a smaller file on this version of enscape and all worked. Please advise

Update:

Deleted a ton of geometry and removed some very heavy textures, purged model and was able to get the output to work, but definitely had to remove way more information than I would have expected to in order to get a file that would open. Going to try and revert to last official release and see if this allows full export.

Downgraded to last official release. Same issue. Started a ticket in Sketchup.

Double checked NVIDIA drivers on Geforece Experience, updated, same result
