Same problem here, UE4 4.19, Kaspersky…
Read all this topic, uninstalling the antivirus is not a solution, this is a workaround.
Topic created more than 3 months ago and still no solutions for this?
May I ask you if you are really working on it? 3 months… It’s not like if you were a little company with few developers… 700 employees in 2018.
What is happening here?
