Does this issue occur when all extensions are disabled?: Yes/No

VS Code Version: 1.79.2

I use the LIVE SHARE extension, and while programming in parallel with a colleague, I shared the collaboration link with him. It accesses normally, but after a few moments, I want to keep track of where it is working, but it is not visible as a participant in the "SESSION DETAILS" section, but I do notice that it opens files, modifies them and saves normally.
Just in case, I haven't shared the link with anyone else.
Obviously this is a very serious security or control problem.
