Tyche demo xml and widget download problem

Dear Sir / Madam

Tyche Demo Version 1.1.4 I’m trying to use the theme in wordpress 5.5.3. I am getting an error while installing the plugini. I recorded this situation on Video. I am sending you the link of this. Also, it doesn’t allow me to install TGMPA Plugin from Recommended Plugins He says you are not authorized.
It also does not allow downloading of XML and widget files as I looked today. Help please
