TVPaint 11 Pro 64bits quit unexpectedly at launch

[ACHE]

Hello,

Today, TVPaint 11 Pro (64bits) no longer opens and a window opens directly saying that "TVPaint quit unexpectedly".

I am on:
Yosemite 10.10.5
MacBook Pro (Retina, 15-inch, Early 2013)
2.4 GHz Intel Core i7 processor
8 GB 1600 MHz DDR3 memory
Graphics Intel HD Graphics 4000 1024 MB

I know it's recommended to have more RAM than that, but it worked before, since I got it, since December 2019.

I was downloading 2-3 programs from the internet (related to my camera to use it as a webcam, not related), then I wanted to open TVPaint and it didn't work, so i closed all open apps, tried again, still not, so I deleted these programs, emptied the trash, restarted my computer, and TVPaint still does not open ...

Is my computer dying? RAM that is no longer powerful enough? Do you know this bug?
Thanks for your help!

Hello,
I found the problem by myself. This CamTwist app was improperly deleted and, for mysterious reasons, hidden files in this app prevented TVPaint and even Photoshop from launching.

Glad to know that everything's okay now
