League of legends only work with Behavior shield disabled

I tried 2 times
With behavior shield enable, League of Legends client cant login saying than something goes wrong
When disable behavior shield, can login as usual

Avast free version 20.2.2401
Windows 10 64-bits

EDIT 2:
After login, can enable behavior shield and play without problem

With behavior shield I get this error from League of Legends client
