Hi,
I have a weird issue with my MacBook Pro 16" (i9 2.4, 5500m, 32GB RAM, Big Sur 11.4). Randomly the screen goes black for 2 or 3 seconds at startup or during work. It happens both under charge and on battery and both with integrated graphic and MacBook display and external display and dedicated GPU.
Should I contact apple or there is a solution?

And it deletes some system caches, including font caches and the kernel cache,
which will be created again automatically as needed.
