Issue with Specific Embed Causing User Logout

I’m encountering an issue where embedding a specific piece of content via an HTML iframe in my Bubble app causes users to be logged out. Interestingly, this problem doesn’t occur with other embeds, only this particular one.
Has anyone experienced something similar or have insights into what might be causing this specific embed to behave differently? Any suggestions or guidance would be greatly appreciated!

Thank you in advance for your help!

Forther information the logout happens only when the embed is present on the page and the user does an acction that either changes or creates a new thing.

The embed is dynamic and pulls the data from my bubble app.
