I’ll answer with this matrix:

What Kirby version starts requiring php 8?

Leaving the PHP support history for Kirby 3 here for reference 3.0.0 Drop support < PHP 7.1, support PHP 7.1 - 7.3 3.3.2 Add support for PHP 7.4 3.4.0 Drop support for 7.1, support PHP 7.2 - 7.4 3.5.0 Drop support for 7.2 , add support for PHP 8.0 3.6.0 Drop support for 7.3 3.6.1 Add support for PHP 8.1 3.8.0 Drop support for PHP 7.4, support PHP 8.0 - 8.1 3.9.0 Add support for PHP 8.2 4.0.0 Drop support for PHP 8.0, add support for PHP 8.3

So, your 5 year old Kirby version is not compatible with PHP 8 and you need to update.

If your website is 5 years old, it’s probably still on Kirby 2, I guess (Kirby 3 was released early 2019.

Hi texnixe,
my last Kirby is 2.1.1

As I already wrote above, you either have to revert to your old PHP version, or you have to update your Kirby version, which will require a little work depending on the complexity of your project (in particular regarding plugins). A simple project is usually relatively easy to upgrade.
