Fenix 7 randomly crashing after 14.68

After I've installed 14.68 I've had my Fenix 7 Sapphire Solar crash/restart multiple teams per day in watch mode. I wasn't doing anything. During this time, it lost a few hours of 24/7 tracking data such as heart rate and body battery. 

I've already tried rebooting and soft-resetting the watch as well as doing a hard reset and a backup restore.

Is anyone aware of any issues or does anyone know how I can solve this?

Thanks in advance!
