I had a similar problem, but instead of deleting it, I added a fake(do nothing) LevelSequence under the mentioned directory.
below you can find my error message
“UATHelper: Packaging (Windows): LogStreaming: Error: Couldn’t find file for package /Game/NewFolder/NewLevelSequence requested by async loading code. NameToLoad: /Game/NewFolder/NewLevelSequence”
Solution:
Create a folder named NewFolder(folder name can be change. Folder name must be the same name which is mentioned in the error message) and create a fake(empty) NewLevelSequence(Sequence name can be change. Sequence name must be the same name which is mentioned in the error message) under this folder
