game crashes every time, doesnt matter if modded or not

Your report is incomplete without crash log/report (minecraft/crash-reports/crash-<DATE>-client.txt). The current log you provided doesn't show anything that could cause the crash.

Probably a duplicate of MC-34749. Please check that report for more information about it.

Try using Minecraft 1.8.8. Also, please don't mark 1.8.8 as affected when you are using 1.8.

@unknown 1.8.8 is currently the oldest thing you can set as affected, he just grabbed the closes version possible

So, how can i solve this problem??

See MC-34749

If that won't help, please use the Mojang Support Center.

So i need to uninstall avast free antivirus?
But mc worked without any issues since i got it until date while i already had avast installed
