Which version of PHP 8.x? Noting that Joomla 3.9.20 is four years old (released in July 2020). PHP 8.0 was first released in November 2020.
I would say you're better off using PHP 7.4 if you can. Then update to 3.10.x which "may" work with PHP 8.0 or perhaps 8.1 (but will depend also on the extensions used).
You might have to do the update offline using a localhost setup such as with Wampserver, which enables you to install various PHP versions including 7.4.x (see https://wampserver.aviatechno.net/).
Joomla 3.10 has now been out of regular support (system updates etc) for 4 months. To keep getting regular updates (security patches only) I believe you now need to subscribe to the long-term support - see https://elts.joomla.org/.
