MH Wilds Connection Issues S9052-TAD-W79T

Hello, I have an issue with MH Wilds when ever i try to connect to a lobby or try to do any online activity in the game i get the error S9052-TAD-W79T on my Windows PC.

I also got an Asus Xbox Ally X running on Bazzite and i tried it there too with the same account and the same network and there i can connect without issues.

I also tried to connect my PC to the internet using my handy as a hotspot oddly enough that works too.

So:

PC + Homerouter doesen't work

Ally + Homerouter works

PC + Iphone hotspot works

I searched online and tried various solutions that were recommended including:

Restarting my pc

Reinstalling the game

Restarting my router

Disabling Ipv6

Turning off my Windows Defender and / or try to add an exception for Monster Hunter Wilds

Setting my DNS server to 8.8.8.8 and 4.4.8.8

Flushing my DNS-cache on the Terminal with ipconfig /flushdns and netsh winsock reset

Switching my network from public to private

Deactivating the ip-helperservice IPHLPSVC

Connecting through both Wired and wireless connections

Resetting my Windows network settings multiple times

all this in various permutations with each other

I also tried to work with gemini to find a possible solution but to no avail.

I clocked about 480h in this game before and didn't have this problem before but i took a break a few months ago and wanted to get into the game again after the recent news on the expansion. Now im just sad that i can't play the game properly anymore :/

If anyone has any idea of what else i could try it would be greatly appreciated. I probably won't respond right away i was spending hours now trying to solve this and now im just tired and probably will go to bed but I will be reading this tomorrow if anyone responds. Thanks in advance!
