It worked fine before until now, maybe it had something to do with upgrading from Joomla 4.2.6 to 4.2.7 today?
On my site there (Ja Teline V) is a menu item that's set to "Category List", to show basically all articles published as intended. Today it shows an error "Attempt to modify property "params" on null"
Enabled logging and it shows
#Software: Joomla! 4.2.7 Stable [ Uaminifu ] 31-January-2023 15:00 GMT

Works on cassieopia (just to test), but not usable on my default template JA Teline V, any thoughts on how to fix this?
