This happens for every collection where I try to manually trigger the action.
The same scheduled actions when should be trigger does not do anything

If I restart the Maintainerr container/application, the manual trigger works again for a while. However, after the normal scheduled rules run, the same problem comes back and the manual trigger fails again with the same message.

It looks like Maintainerr may think that collection handling or rule execution is still running, even after the scheduled execution has already completed.

To Reproduce

Steps to reproduce the behavior:

Create one or more collections/rules in Maintainerr 3.8.0.
Configure a Sonarr action, for example:
Media type: Seasons
Sonarr action: Unmonitor season and keep files
Let the normal scheduled rules run.
Open a collection/item that matches the rule.
Click Trigger now.
The action fails and Maintainerr shows:
Collection handling is already running. Try again when the current collection or rule execution finishes.
Restart Maintainerr.
Try Trigger now again: it works.
Wait until the scheduled rules run again.
Try Trigger now again: the same error returns.

Expected behavior

I would expect Trigger now to run the selected collection action when no collection handling or rule execution is actually running.

If a collection/rule execution is really still running, I would expect it to finish and then allow manual triggering again.

Screenshots

I attached screenshots showing:

The error message displayed by Maintainerr:
Collection handling is already running. Try again when the current collection or rule execution finishes.
The configured collection/action:
Library: Programmi TV
Media type: Seasons
Sonarr server: raspsonarr
Sonarr action: Unmonitor season and keep files
Take action after days: 3
Example rules used in the collection:
Sonarr - Status (continuing, ended) equals Continuing
Sonarr - Has unaired episodes equals False
Sonarr - Has season finale episode equals True
Sonarr - Number of missing episodes in season equals 0
