2019 R2 SP1 + CMMVe problems

Lot of crashes today, trying to execute an old program (which worked on 2018 r2).
I believe that the problem comes from a new lightning option (at the bottom right of the light window).
I'm unable to change to ON the first setting of light into the command window (<OFF,50,ON>.
In my program which crashes, it's <ON,100,ON>, the light is very "strong", and I can measure the equator of a white sphere with black background.
If I click on the new button, the light becomes "strong", but decrease while I select test...

Any other guy saw it ?

Ah, I forgot, the rotary turns !
