Perforce: no assets to check in

Suddenly Perforce integration broke for me and I cannot figure out how to reset it.

I can check out, mark for add, mark for delete and sync files, but when I try to submit I am always presented with the error: "No assets to check in!".

In the Output Log I can see a bunch of messages like:

SourceControl: Path 'C:/Program Files/Epic Games/UE_4.26/Engine/Content/...' is not under client's root.
SourceControl: Path 'C:/Program Files/Epic Games/UE_4.26/Engine/Plugins/2D/Paper2D/Content/...' is not under client's root.
EditorErrors: Warning: No assets to check in! 

I disabled and enabled again source control, synced the content folder, but nothing seems to help. Everything works from P4V.

Any suggestions would be appreciated.

Got the same issue but with Git… anyone know whats up?

Getting this also

I can’t figure it out
