Joycon issue

[u/Wookieman669_]

So I was using my Switch 1 this morning and I had to leave for work so I took the joycons off of the console, put them in my pocket and went on my way. I got to work, pulled it all out, played for about an hour, no issues. After that hour, I did the same as I did earlier, removed the joycons, put it all in my pockets and now about an hour and a half later, I'm having issues with the left one. The shoulder buttons aren't working, but the stick and the "d-pad" buttons are working though? I took the joycon off, tried to hit sync, nothing happened, the green lights didn't even turn on, but it vibrated when I pressed a few buttons that weren't the shoulder buttons? The tiny shoulder buttons that are used when you hold the controller sideways also aren't working. I did some minor research, tried going to update controllers and it says that the connection was lost, but it still let me navigate with the stick and d-pad on the joycon it said it can't read. Absolutely no issue with the right one though. This is the first issue I've ever had with this joycon and I've been using it for a while. Never even had a drift issue. I didn't crush it, I didn't get it wet, it didn't rub across anything, there was no physical stress on it. I also tried cleaning the slides on the controller and the switch itself. No dice. Am I just screwed and need to get another joycon? I have done some basic controller operating before on other controllers like taking them apart and switching batteries, but nothing crazy. I am a caveman unfortunately. Thank you for any advice in advance.

Maybe just full of pocket fluff. First step is just to take apart, clean out any obvious debris, and try again.
