Black screen after installing update

Hi,
I have a problem with a project that I'm working on.
After installing the new update for Resolve 17, my old project won't work properly.
All my media are showing a black screen, and the timeline also.
(I'll insert a picture)

My laptop specs
HP Pavilion Gaming 15-ec1061nm
AMD Ryzen 5 4600H 3.0GHz 16GB 512GB SSD nVidia GeForce GTX1650 4GB

Try a clean and complete install, not update, of the GPU driver.
