"Error - accessibility service not running"

I use Tasker with the AutoInput and AutoApps plugins across several devices to run tasks.
Lately, I've been having actions randomly fail with the error "Accessibility service not running" despite it running quite happily for months prior.
Using an AutoInput Action to click certain coordinates, doesn't not present an error, but the click does not happen.
The permissions are set as they always have been and I have done nothing to change them. It is as if the service just forgets it has been set up.

The only way I have found to fix this has been to clear the cache and data from the AutoInput app and then go into it to reset permissions.

Is there a way to prevent this error from occurring, rather than having to manually fix it afterwards?
