What could be causing one GFCI to be hotter than the rest when all other readings seem normal in the panel?

Hey, so I used a thermography camera to check out these lugs and they were reading at 145 degrees. I decided to look into it because the main breaker had tripped. Everything in the panel seemed fine, except for one 20A GFCI that was a bit warmer than the others. The amp readings per phase were 93 and 84 with the ACs and double ovens running. Any ideas on what this could mean?
Do a service load calculation. Check torque on meter and main lugs. Check ground current with respect to service neutral current and the two line currents.
