FM Go Crashing
We have several layouts containing Portals inside of Slider Windows, inside of a Popover - works great in Go 13 and Crashes Go 14.
All in one file?
Have you used recover to check the file for damage?
It's not unknown for a file to have hidden damage that causes no apparent problem until you upgrade to a new version of either the database application or the OS.
You might want to try creating a brand new copy of the layout with nothing copied over from the problem layout to see if it also crashes on you.
