Does it still happen in a new profile (without signing into sync account)? An easy way to test a new profile is to install Developer Edition and see if it happens there or refresh your existing profile.

You appear to be using Dr.Web security software. Did you check for issues caused by this software by booting Windows in Safe Mode with Network support like I suggested above ?

Hi, yes I using Dr Web security space 12 but if it is the reason why it is not affecting/conflicting with MS Edge? Not tried yet because I'm not feeling safe to do networking without antivirus protection.

You will still be protected by Microsoft Defender when all third-party antivirus software is disabled.
