iPhone 16 Pro Max keeps crashing after iOS 18.2.1 update

My iPhone 16 Pro Max randomly crashed twice in two days. When it happens I do not get any notifications and it does not connect back to WiFi till I put in my password. Then it connects to WiFi and all my notifications start appearing. The battery graph also has a huge gap in it from the time it happens till I unlock it. The first time it wasn’t charging when it happened, this time it was on my MagSafe charger overnight. This Reddit post is having the same issue.
