My computer runs Windows 11. Previously, I had client version 8.4.4. Everything worked fine on it.
But for some reason, I decided to update to 8.5.5.
And this version doesn't detect the GPU on my computer.
The worst part... I installed client 8.4.9, which worked before. But now the GPU isn't detected on it either.
I haven't changed the Windows version, and I haven't updated the NVIDIA drivers.
I just updated the client, and now the functionality is broken.
Could you tell me what the problem might be and how to fix it?
