Animate 24.0.8 GIF Export Fails Due To High Memory Usage

I have a very short animation (48s at 12fps) that i was able to export as a video but  cannot export to animated GIF; have tried on two different machines and both machines it just freezes and errors out. On the Mac it pops up a system dialog box saying memory usage is maxed out and that Animate is taking up 42GB of memory (no other programs or applications are open).  I have no extensions or plugins running. 

I have searched this forum and havent found a post like this - do i have some settings incorrect perhaps ? its driving me nuts. I know i can export my video then convert that to a GIF but im trying to limit compression as much as possible as its very vector and text focused. 

Have tried on a windows microsoft computer as well as a mac. all my updates are up to date. any suggestions are welcomed and thank you in advance .
