Editor Stuttering When Offline(no internet)

I downloaded ue4.25.1 (latest version) and noticed periodic screen freezes Only when my internet is disconnected !
Both crash report and bug report are disabled So what is this secret internet checking thing inside Unreal Editor?!
Please someone save me im going mad!

thankfully found a post on reddit that said turn off ENABLE TRANSPORT in UDP MESSAGING and fixed the constant stutter!
