Database filters in pages no longer work

I'm not sure if it's because of the 4.7.16 update, but the database filters in pages no longer work. Database categories work. However, the filtering of the data records no longer works, where these are only saved in a database without categories.

Since we are still in the development phase, we have reset the templates to IPS default, but unsuccessfully. We also deactivated all plugins. But also unsuccessfully.

We have checked the databases and the fields, but have not found any deviations. At least yesterday afternoon, after German time, everything still worked.

Since then, this error message still appears in the sidebar for database filters.

[[Template cms/front/widgets/DatabaseFilters is throwing an error. This theme may be out of date. Run the support tool in the AdminCP to restore the default theme.]]

I would be grateful for any constructive advice on what else to check.
