Submit to Perforce - "file(s) not opened on this client" error

Hello, I am trying to set up multi-user editing in UE5.3, but I am having issue submitting changes to source-control.

Perforce and network seem to be configured correctly, as I am able to create depots, workspaces and even distribute the UE project. Inside of the project, I have connected to source control, created session that all my machines are able to connect to, but when I make any changes (even a simple placement and moving of a cube) and try to submit the changes, I get an error Failed to check in files and upon opening the message log, I see a message related to the objects I have manipulated file(s) not opened on this client

Any advice on how to fix this issue? Thank you in advance
