Wavelab12 crash opening supervision and now wont start anymore

hi everyone i have a crash who makes no sens, i had a 5 audio files in open in wavelab.
i simply open supervision and checked the audio ; worked grat for all the hours i use it. then i closed wavelab. and this morning i can’t open wavelab. has soon as the window open and supervision plug in show with the work windows with audio files , wavelab shuts down.
i don’t get any crash messages. but i know its due to supervision since it is the only plug in open. how can i disable supervision before opening wavelab12 . because i try uninstal and instal it again but it opens with supervison plug in open so does the same it crashes right away after opening wavelab. i never had that problem before neither. i use to chack many times tracks with supervision and never had that
Thank you all

This is not necessarily supervision.
Anyway, you can start WaveLab by pressing CTRL (Command on Mac)

i uninstaled wavelab completly and restarted my computer, i reinstaled it , now it had to read all the plugs again and i could open a empty window who did not load right awy supervision and it worked. i reopaned all the track i add to analyse. but now i’m almost afraid to open supervision again. if the problem happen again i don’t see what other thing then supervison that could create the crash . ps i aslo just updated my nvidia drivers now after uninstaling wavelab and before reinstaling it .

Your idea that the problem came from supervision is not proved, I think.
In any case, you do not need to reinstall WaveLab. You can just start WaveLab with the modifier key pressed, as I have mentioned before.

i will try tomorow , thanks for the advise
