Freeze & Crash to Desktop When Expanding in Flight Menu's

Chosen flight starts OK. I use a second screen to pin map, ATC communication and Camera View menus during flight. I can pin the menus with no problem, however, whenever I expand by dragging the ATC communication menu to a bigger size, FS2020 freezes and crashes to the desktop. Only started happening in the last couple of weeks, but happens every time unless I start in Safe Mode.

Not using developer mode.

No unofficial add-ons.
