No Wi-Fi after IOS 18.5 and later

Last month, I updated my iPhone from iOS 16 to 18.5, and ever since then, my home Wi-Fi just stopped showing up on my phone. Like, it’s completely missing. But here’s the thing — the Wi-Fi works perfectly on my other devices that are still on older iOS versions, so clearly the problem started after the update. I called Apple support, and they told me it’s my ISP’s fault. Then I called my ISP, and they blamed Apple 🙄 Like hello?? I’ve tried everything — removed my VPN, reset the network settings, all the basic stuff, and still nothing. Apple even checked my phone and said the hardware is fine, so why can’t they just admit it’s the update?? Some Wi-Fi networks show, but not my home one. It’s honestly so annoying and stressful, and I’m just really upset because I feel like no one’s actually helping fix it
