Yakuza 0 crashing and causing WiFi to stop working

Hey,

Just want to express an issue my brother is having with his computer while playing Yakuza 0 on pc game pass to see if anyone knows a way to help or give me a route I haven't taken so far to solve the problem

The reason I specify the game is because he hasn't experienced the problem before playing this game and hasn't played anything else so I am unsure if its a computer issue but with my experience with pcs I don't believe it's a pc issue. I believe it has something to do with the xbox app or the game itself.

Checking pc components, it is clear it is not a result of bottlenecking or overworking components, equally its not overheating.

The issue that occurs ranges, a few times it has popped up with the generic error code claiming something is wrong. Sometimes it says nothing but the connection issue occurs. Sometimes the game closes itself . The connection issue is unable to load apps like discord or search things on a browser but able to open new tabs. If he closes the xbox app things start working like usual again. If yakuza stays open he has to close that too.

I have trial and errored to try to figure out the issue, updating drivers for everything. Deleting the xbox app. I have suggested deleting and reinstalling the game but as he is close to the end he doesn't seem go bothered to do that.

At a lost for what to do or suggest. I want to know how to fix this issue so he can finish the game with peace of mind but also if this is not a game exclusive issue, and instead is a xbox app or pc issue generally. Some way to solve this would be massively appreciated so I can stop this from happening again and if it happens to me I can solve it myself too.

For context I don't believe the components matter at all as they are not under any stress and it isn't a budget build. But it is operating on Windows 10

If anyone has potential solutions I haven't thought of yet will happily give them a try. This such a bizarre and random issue that thought my exploring of forums and using my own knowledge has taken us nowhere.

Any help or advice would be appreciated

Thanks

:)
