Unreal Insights "ExecuteForegroundTask" causes huge level load time

Yesterday a problem has appeared out of nowhere. I thought at first that it could be due to the huge amount of apps I had open at that time but today the problem was still ongoing and I went into Unreal Insights to discover the origin. I can’t find any info on what could this task refer to and I can’t remember what change have caused it because most of the things yesterday was usual stuff like adding more content.
