With the collaboration of Jean Lan (Cyberlink Support) found the cause of the error (Tools video disappears) and its side effects.
On my PC, changing the default timeout transition to 1.8 or 1.9 causes the error.
Only with added transitions (CROSFADE)
Time pattern (2.0 Cyberlink)
Runs normal for other times.

Hang on a sec Playsound- I would not mark this as "resolved" since the issue is not fixed.

I use a faster 0.7 Transition timing and it happens with the Crossfade transition.

I have never used 1.8 or 1.9 transition timing.

Having to use the default 2.0 Transition timing as a work around is way too slow.
Like watching paint dry.

Put as solved, because now I can work normal knowing and avoiding what causes the error, already solves for me.
I believe Cyberlink should fix the error at the root soon.
I checked here, transition time 0.7 causes the error, with (0.6, 0.8 and 1.0) works well, for me.
Note: The project may have transitions with different times.
In (Prefereces / Editing / transitions) should leave 2.0, or another time that does not cause the error.
