For about a week the game's been crashing when it starts to load the wordl.

I've tried stuff from "a few" YT vids but nothing works. Please help. I use windows with version 1.10.2.

Thank you.

This is usually caused by an Antivirus program, or another program that is conflicting with Minecraft. What Antivirus/Firewall software do you have installed?

I have Avast, Malwarebites and Superantispyware.

ADWCleaner is an utility to clean a PC which may be infested with malware. Download it here: https://toolslib.net/downloads/finish/1/

Have it run the Scan, then do a cleaning. If that doesn't work, you may need to uninstall Avast, restart the computer then test Minecraft. If it works, reinstall the latest Avast!.

Tried everything, didn't work. Same crash report.
