Black Shadow Streak line

Greetings!
I just encountered a really weird issue, I load up my project as usual and for some reason, there is black streak of shadow all over the project, this never happen before as I just boot up the project again from couple hours ago without this issue.
Picture below, this black line is consistent as long as there is lighting in the map

I assumed it has something to do with Point Light so I switched them all off and the shadow streak is gone, but once I turn them on again it appear back. I also tried to rebuild lighting but it din’t help, switching the point light to static ro dynamic did not help as well.

does anyone have a solution to this? the point light took a lot of work and I can’t work without them but it impossible to work with those black streak.
Thank you very much for your help and time in advance!

Does this happen when you set the viewport to unlit?
does this happen when you press “G” in the viewport?

my apologies for the late reply, I keep refreshing but it show 0 replies for some reason so I though this was dead…
when I set the viewport to unlit, the black streak line is gone. When I press G in the view port the streak line is persistent.
