Davinci does not open

Hello, I currently have Davinci Resolve Studio 18.6.6 yesterday I was using it as normal, but today when I try to enter the program does not open, or it opens but as soon as I open a project it closes. I tried to use the 19 beta but it didnt work, also I erased all the cache of the program but still nothing, I dont know what else to do, I would like some help

You don't mention OS but it's likely a windows OS update changed the GPU driver.

If re-installing the correct driver for your specific GPU doesn't work, please see the FAQs for details on what to report so someone can assist.
