Floating webview problems persist with my profile sessions

I have some actions for opening a floating webview. For example, I have one that opens Telegram. However, after I open my session, it later automatically closes my session and I have to open and open again. I use the option "Pre-load immediately after BTT is launched", but I don't know if that causes any problems. Can someone please help me? I want to keep my session open. Is that possible?
