hah, Finally I Fix the Problem 😁 According to the developer site, the main program folder after installation at this address is "C: \ Program Files (x86) \ Common Files \ BattlEye", not the folder at the game's installation location. I mistakenly added the BE service directory in the main game directory to the object exclusion list, and all running programs were blocked. To fix the problem, we need to add the original service folder address ("C: \ Program Files (x86) \ Common Files \ BattlEye") to the object exclusion list. “But this will temporarily fix the problem. The problem can be resolved when the antivirus software is not considered a malicious program. 😉
