i soldered new right and left switches on my mouse, now only the right click works, i have tried difrent switches and it still wont work, it might have somthing to do with that thing peeling?

Managed to put a jumper wire on the trace, and that fixed it, jankiest job ever tho ๐Ÿ˜‚

Seems like the board track is damaged. You need to check with a meter and make a jumper on it.
