Looking for some help troubleshooting electrical problems in f-150

I have a 2017 5.0 f-150 that I haven’t driven that much lately.. the other day I pulled it out the garage to run it (it hadn’t been ran in about a month) and it started up just fine. I drove around for a little bit, then went home to park it. After parking, I turned the truck off but the radio stayed on.. I thought that was strange so I got out, shut the door, and it never went off. So I got back in, turned the key on and off a few times, moved the truck a little, and shut it off. The radio went off but the AC control lights stayed on. So I started it AGAIN, and the dashboard, ac, and radio was all off and won’t come back on. The ac doesn’t work and none of the needles or lights on my dash move.. I’ve tested the battery and it’s fine, but I’m really not sure where else to look besides pulling out all the fuses and checking them, which I’m about to do right now
Any help or advice would be appreciated. Trying to avoid going to the dealership

Look for rat and or mice droppings
Look for nest eapically in the air filter housing and inspect wiring harness for signs of chewing

I'm guessing if there are no damaged wires it's going to need a body computer.

Original battery? First thing I would try is putting a battery charger on it for a while and see if a fully charged battery solves the problem.

these new batteries are finicky and if you don't drive the truck often, or have it plugged up to a charger, weird things can happen. My auto stop routinely doesn't work (which is optimal but id rather it not work because I made it not work lol) then I drive a 3 or 4 hour drive and it'll get enough battery charge to get it working again.
Although your problem sounds a little more intense. I'd mosey on over to the f150forum and search it or make a thread about it, I guarantee one of those old baws will know what's going on just from your description.

Battery is relatively new. Put a battery tester on it and it was dead today obviously. Couldn’t really do much cause of the nonstop rain

Which forum would you recommend specifically?? I browsed briefly earlier and my problem isn’t very specific so it’s hard to search for

Can I take one guess? Does it have a sunroof?

Full battery and wouldn’t start or even unlock with the key fob

This is unbelievable but someone I know had similar issues. Ended up being a leaking tail light. See if any of your tail lights have water in them and then drain and reseal or replace.
ETA make sure you give everything time to dry out before putting it back together. And this was related to blind spot sensors. If you don’t have those it’s not likely your problem.

The reason I asked about the sunroof is my brother just had major trouble on his 17 F150 with a sunroof. Ended up having a leak that went down into the electronics. The truck would do crazy stuff with the lights, try to start, horn honking etc. Sometimes in the middle of the night. Total mess. He just sent it down the road last week.
I saw a broken down newer F150 last weekend and the guy was cussing up a storm. I texted my brother and he said "does it have a sunroof?" Yes it did.
I wouldn't doubt its some leaking/water issue.

Id just make a thread on the general board for the 15-17 body style. try that link. Yes the sunroofs seem to cause a lot of problems, I think some higher models you may not even be able to get them without a sunroof. that would piss me off lol. But yeh it sounds like a grounding issue of some kind, or definitely battery related but I'm no expert, but alot of those ol baws on that forum been driving fords since the model T.

Good luck. if all else fails, worst case you could run it by a local dealership but with business being so crazy idk if they'll try to uncharge you more than what its worth to look at it.
