AC Issues

About a year ago whilst backroading I got in a little disagreement with the asphalt about how many G's my 14' ST should pull on a corner, and unfortunately I lost the argument because it threw a little comeback about dust, and consequently I gave the mountain a little kiss. This cracked my bumper, radiator/fan shroud, among about a dozen other pieces of plastic I had to painstakingly identify in splinters. It's all back together now, but I'm still having issues with my AC.

Obviously, when I replaced the radiator and all that jazz I knew I would need to recharge it with freon. I did this and had no luck, and a few months later it's still steady at ~30psi so a freon leak is unlikely to be the issue. So, I began the deep dive into the electronics. The cabin air temp sensor that has been mentioned in other forums seems to be completely fine, but I may replace it just in case. I checked the fuse box for the compressor and it was still good.

I began to think my compressor clutch just wasn't engaging but at idle when I'd press the AC button I'd hear the rpm's drop as the compressor clutch would engage, so I would figure. I decided on a visual test, so I located the compressor in the bay and watched as the center would spin when the AC was engaged, and would be still when I would turn off.

So, the air compressor clutch seems to be good, the electronics seem to be good, and the refrigerant system seems to hold pressure. What else could I be missing?

Also, here's a flic of the shitbox post disagreement
