Why all the tabs are erased when I turn on my desktop pc. I chose in Settings custom homepage but it does not make any difference. Since this AI Beta version was introduced

Need help how to fix the issue described above. I do not want to set the websites in tabs every time I open Fox. I use Fox for years and I did not have any problem with tabs until now when AI Smart Window Beta was introduced. It really bothers me to go and select the websites I need every time I start my PC. Thank you.
