CiviRules vanishes, gives errors across Civi, won't uninstall (2 sites)
I tried to update some extensions today and got an error "Error: invalid entity" - which when I check ConfigAndLog references CiviRules. Realise CiviRules menu isn't present any more, but can't disable it, as get same error. Disable in the dbse, and try to uninstall from the UI and get a new error "API (CiviRuleAction, get) does not exist (join the API team and implement it!)". I get the same error across Civi - clearing cache, upgrading other extensions.
Not sure how to manually uninstall CiviRules safely/fully as renaming the extensions folder / empty tables doesn't seem to help.
I checked another v similar site (Joomla4+Civi5.69+PHP8.1) and it's just the same, so it must have been quite recent (last few weeks) that something changed - and seems more a bug than a one-off.
