hello
i'm having the same "operand stack overflow" problem. i looked at the other crash report (above) but didn't find the three entries that you recommended to be removed. After running the report i removed " crosshairmod-v0.8.2-forge-mc1.12.jar" and relaunched minecraft forge and got the same error. can you take a look at my crash report a give suggestions?
Here is a link to my crash report: https://pastebin.com/xyXDB3PL
