Plugin failed to load properly

I’m having an issue with using the Download Monitor Button Block within the Gutenberg editor. The error is triggered by something I’m not familiar with.

I was at first trying to use a custom template but have since reverted to the default template.

This is the error I see in the recovery mode:

WordPress also generates this error:
