Cleanup Tasks App - error

Hi everyone,

I just installed the plugin Cleanup Tasks, version for Studio 2019, on my PC (Windows 10, Studio SDL 2019 Downloaded from the SDL App Store.

When I run a Cleanup Source task, I get the error message "Index was out of range. Must be non-negative and less than the size of the collection.Parameter" after clicking on "Next". Studio stops working and I have to restart it.

If I don't click on "Next", but on "Finish" instead, the plugin works but doesn't change anything to the source (the tags are still there).

Any idea what can cause the problem?

I have tried to uninstall the plugin and remove all traces of the install on the various relevant folders, before switching off the machine and re-installing the plugin.

It did not work.

Thanks for your help.
