Strange lightbake behaviour that i havent seen before. Black spots

Hey,

I have this strange thing that never happend before. Normaly when i bake everything is good but last week at work i noticed these weird shadows or black spots growing. And I dont know why... i asked around on the Unity Reddit but still haven't solved it.





What i did notice is that when i turn off filtering it stops but yeah it looks horrible. but the weird thing is that some of my collegues also noticed this but we all have different computers.

I am hopefull that someone here could help me. i am almost pulling my hair
