AI function constantly disappearing

the AI functions disappear several times per day. I have a couple workarounds that fix the issue at times - like opening a new Storyline file, or opening another Storyline file. However, frequently I have to completely shut down my computer altogether.

I see from other discussions that I am not the only one having this issue. It really needs urgent addressing as it heavily effects productivity.

Is there a new solution I am not aware of?
