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?

Safe mode prevents your Mac from loading certain software when it starts up, including login items,
system extensions not required by macOS,
and fonts not installed by macOS. It also does a basic check of your startup disk,
similar to using First Aid in Disk Utility.
And it deletes some system caches, including font caches and the kernel cache,
which will be created again automatically as needed.
