I am using Live 10.1 it’s the latest version.
No any automation written.
Midi track send FX also occur this issue.
Delete that return track and new another one the issue still there.

Thanks in advanced.

Right-click the "S" Solo Button and check if the "Solo In Place" option is enabled (has to be On for the return tracks to be audible).
