All third-party script UI panels become unresponsive

[Editor5FCF]

Hello.

 I hope this post finds you well and safe. 

 Throughout the last few interations of AE (I can't remeber how far back, and currently on V18.0 and Big Sur 11.2.1) during use all third-party script UI panels become unresponsive. 

 A restart of AE fixes it and there are no error pop ups during boot up or use.

 But then after a seemilgnly random amount of time (could be a minute, or 4 hours), all third-party panels stop working. For excample, TextExploder wont apply, or butcapper, or even tabbing between options on Motion2 wont work.

 I haven't confirmed this, but it might become unresponsive while I'm in another app (Safari, FCPX etc..) as quite often when I come back the third-party panels are unresponsive. 

Anyone expierenced this?

Thanks!
