Problem kind of solved ? It seems that it was my video capture card that caused DaVinci to crash. I don't really know why since I didn't change anything with my set up, but well, unplugged it and now I can launch resolve again.
My original message in case anybody runs into the same issue :
Hello everybody,
Today for an unknown reason, DaVinci resolve studio 17 stopped starting up. I'm windows 10 user, Everything works fine when launching the software, the loading window appears but then, when it disappears the project manager does not show up and DaVinci just disappears in the task manager.
I tried to reboot windows, I tried to launch as an administrator, I tried to reinstall DaVinci but nothing solves the issue.
I'm clueless, everything was working fine yesterday.
Please help me, you're my only hope !
