After a few minutes a at 60' it's extremely unlikely that a rapid ascent kills you or even hurts you unless you hold your breath.I think about heading to the surface, even taking a kick or two. It dawns on me quickly that I won’t make it and/or a rapid ascent will probably kill me.
You shouldn't do it but it's an option, the least desirable one, but an option.
After 2 years without diving at your experience level I would always recommend to repeat some skills just see if you're still familiar with everything. At least the basics. Mask removal, air share, switching regs. Some shops offer short check dives or updates. Those are not a money grab, they really make sense.
Diving in a group is fine but make sure you have an actual buddy and both of you know that you're buddies.
I can't think of any repair the guides could have done near the gauge that would fix getting a water into the 2nd stage. Must have been the exhaust valve.
