Hello, Tokoloshi_45.
Thanks for taking the time in trying that step for your issue. Next, let's see if the same issue occurs in a test user account and safe mode:
How to test an issue in another user account on your Mac
Use safe mode to isolate issues with your Mac
"If an issue doesn't happen in safe mode
If an issue doesn't happen when your Mac is started in safe mode, try restarting without pressing any keys.
If the issue comes back, you might have incompatible login items.
If the issue doesn't come back, it was probably caused by a cache or directory issue with your startup disk, which safe mode fixed".
Also, are you able to connect to a different Wi-Fi network? This could help rule out network issues.
Keep us updated.
