Samsung galaxy Z fold 4 wifi won't turn on.

[Aethel]

Already restarted phone. Reset network settings. It was working last night and this morning. Disconnected when I left home as usual. Tried to turn it on at work and it no longer turns on. It goes grey, tries to work, then turns itself off.

Google isn't helping and neither is the useless Samsung Ai chatbot that's just regurgitating Google results
