Cuelist playback 'flash' option issues

I have found a issue with V3.6.0 where cuelist playback setting 'Flash' or any of the other 'Flash' options 'Flash Full' etc stop working correctly seemingly freezing.

Releasing all lists or pages and restarting playback doe not help the issue. But iff you change to a diffrent 'Flash' option it will start to work again.

This stops the ability to make flash buttons on command keys and alot of other playback issues.

This also affects Group masters when using the Button flash key on a master as 'Flash' or for me preferred is 'Flash opposite' which in turn freezes operation of groupmasters and nothing will fix this besides changing the button option to a different flash option
