On the site I have Akeeba Backup + JCE Pro + Yoursites + D2 Content Pro.
However, after disabling all non-core Plugins the error remains....

Ok. I'll test again with a clean Joomla 3.9.10 on another PHP 8 environment.

Thank you both for your answers @brianteeman + @PhilETaylor
set_time_limit had indeed been disabled.
I've removed it from the disabled functions and the error has been gone.

stumped on same hoster issue with php 8.1 .. in akeeba following code is used to check for function
if (function_exists('set_time_limit'))
{
set_time_limit(0);
}
