Steps to reproduce the issue
- create a contact category
- create several contacts, and put them all in this category
- create a menu item of type "List Contacts in a Category", and set the "filter field" option to "show" in list layouts
- if front end visit that page
- apply a filtering criteria
- apply again a filtering criteria (or simply reset)
Expected result

Actual result

It looks like the limit.start in the session has an object instead of a string or number. This causes a TypeError in PHP 8 (it was a warning on earlier versions). This is unrelated to #37139, that PR deals with caching issues.
The real problem is components/com_contact/src/Model/CategoryModel.php line 295. It reads:
'com_contact.category.list',
when it should be reading
'com_contact.category.list.limit',
since we're trying to get the state of the list LIMIT, not the entire subset of list options in the user state...

after issuing the error, every subsequent visit to the page will lead to the error page.
it is probably related to session cookies: if you wait long enough after the error, visiting the page will show the list.
The same thing happen if you delete cookies after the error: visiting the page will show no error
