CefSharp.BrowserSubProcess When starting LB win11? LaunchBox-13.22-Setup

[Undertherainbow]

 

Does someone knows what this is about? It pops 4 times.

I tried clean install, same thing. 

Im on win11 up to date updates.

Run the installer again over your install. Make sure the installer doesn't try to create a LaunchBox folder within your LaunchBox folder. The install won't overwrite anything and your data is safe. This error almost always occurs when an overzealous AV quarantines the CEF dll. They tend not to like that it opens a browser because bad actors in the past have done malicious web stuff with things like that

Hello.

I do not have overzealous AV. Only windows defender. And its just my arcade machine. No internet browsing either. 

CefSharp.BrowserSubprocess.exe seems to belong to chromium third party plugin?

I already tried multiple times to instal clean. Error pops every time. Its so damn weird. Reinstaled entire .NET package as well.

P.S

I already added folder to defender exclusion. Thats why i ask because i see nothing else that could mess with this.
