It is a known issue with PHP 8+ versions.
Someone mentioned a possible solution until the official staff solves it in the next release:
Change the 518 line of code in system/libraries/Pagination.php, make a type casting on the $this->cur_page variable to string:
From:
if ( ! ctype_digit($this->cur_page) OR ($this->use_page_numbers && (int) $this->cur_page === 0))
to:
if ( ! ctype_digit((string) $this->cur_page) OR ($this->use_page_numbers && (int) $this->cur_page === 0))
