Hi Jorge,
I'm going to disagree with @jmehnert that iPhones don't kernel panic; we've seen far too many examples here on iFixit.
The panics generally come in two flavors, hardware and software. The hardware panics tend to be associated with a specific sensor on the phone that isn't responding and is usually fixed by replacing that particular component.
The other kind, which yours falls under, is a software problem. Apparently iOS 16 introduced some bugs that resulted in kernel panics, and in general the solution has been to upgrade the system to a newer version. I see from your logs that you're running 16.3, which in theory should have contained the fixes for the original bugs, but there may be more fixes in a later version. Here's an excerpt from @flannelist's excellent [[iPhone Kernel Panics|iPhone Kernel Panics|new_window=true]] Wiki article that's particularly relevant to you.

The Watchdog Timeout process checks for overall functionality of the system. If the amount of time between check ins exceeds the maximum (typically 180 seconds), the device reboots to attempt to correct this.
* Rather than a missing sensor as previously discussed, you may also get a check in failure from a software component. ***Springboard***, ***logd***, ***wifid*** or ***thermalmonitord*** (with no reference to a missing sensor) are common. Although these processes may correlate to a hardware component, this is typically a software issue.
* This issue has cropped up commonly in early versions of iOS 16. The solution is generally to ensure you have a backup and restore your phone's software.
* It remains to be seen whether Apple has corrected this with iOS 16.2, but attempting to update is worth a go if you don't want to backup. Try using the Recovery Mode method to process the install to avoid reboots mid process.[/quote]
Long story short, the usual fix for this is to update your operating system. If that doesn't do the trick, then a full backup / wipe / restore may be necessary.
Good luck; let us know what you find.
