AntiExploit blocking Chrome and Edge

Hello.

I am having problems in one client because Harmony Endpoint is blocking Chrome and Edge with no special reason.

I get alert that Anti-Exploit block threat, but i dont find anything that might cause this.

 

Endpoint version - 85.10.0575

 

More info in attach

 

Regards

Pedro

Per above a workaround is currently required until a permanent fix is made available (E86.00).
