OBS Preview Keeps Freezing, but only for FORTNITE

Hi there guys! I've been facing an issue for a while now on my PC.

Everything was running as it should, but then suddenly after an update on OBS, or Fortnite, or Windows, or NVIDIA, or Elgato, idk, everytime i run Fortnite and it reaches the "Connecting" screen, my OBS Capture screen freezes. I use two monitors and Fortnite runs fine after it on Monitor 1, but on Monitor 2, where OBS preview is, i can see that the Elgato Capture Screen is frozen on the "connecting" screen of Fortnite. If i try to play it im able to, but nothing is captured other than that screen. Im also able to hear the audio just fine while playing, and am able to capture the audio just fine.

Oddly, this just happens to occur with Fortnite so far. Tried other games and it runs and capture fine. Also, i capture the screen together with my facecam at the same recording, so i use a different resolution. The camera is connected with an Elgato HD60S wich keeps working normally without being frozen. Just the main gameplay Elgato 4K Mk2 screen freezes, and like i said, only with Fortnite.

I already tried:

- installing/unninstalling OBS
- Disabling Vsync for OBS because i found some people saying that solved for them after latest Windows 11 updates
- Disabling MPO
- Disabling HAGS
- Updating GPU Drivers
- Updating OBS to the latest version
- running OBS on admin

This is the latest log: https://obsproject.com/logs/glhaLgGfOLHRbBI5

I also updated my GPU today and went from an RTX 2080ti to an RTX 5080 and the issue remains, so its not GPU related, at least not hardware issue.

As a workaround to keep capturing Fortnite, i've been capturing it on my PS5, wich is also connected to an Elgato 4kX, but i would love to be able to capture it again on the PC. Not sure if its an Unreal Engine 5 thing as well..

What can be happening and how do i solve this? Would really appreciate any help.

Kind regards

Forgot to mention that it only resumes working after i close fortnite, click on the Eye button at OBS for the frozen screen to hide it, then click again to show again and as long as Fortnite isn't running, it starts working again. And i capture other games without any issue.
