Topic: Joycon not attachable due to a screw stuck in the joycon rail

So I didn‘t use my switch in months and picked it up again for Pokemon, but when I wanted to enjoy it a bit in Handheld mode I realized that my right joycon wasn‘t attaching to the Console. When I looked into the rail or whatever it‘s called I saw something that looks like a little screw but I can‘t get it out of there (Don‘t ask me how a screw got there, I have no idea tbh). Should I try to disassemble the rail and if so, anyone knows if that‘s hard or has a guide for that?
Thanks in advance

First off you should contact Nintendo Support if in Warranty. If out of warranty you should check to see if and where that screw came from.
