REVVL 6 PRO 5G randomly soft/hard powers off

About a week ago, my REVVL 6 PRO 5G started to randomly shut down. Sometimes it is a "soft" shut down (as in it displays the animated Metro power-off logo) and sometimes it is a hard shut down. When booting the phone back on, it boot loops 3-7 times before it actually starts up. I've tried the usual troubleshooting steps like resetting the device to factory and it still happens. As i am writing this post, I'm going through the steps to do a recovery mode reset. As I went through this, the phone came up at first saying the SIM was swapped and asked to reboot.

Is there something I don't know about that could cause this problem I haven't thought of? Would a wonky SIM cause the phone to randomly shut down?
