Can't install with Craft CMS 3.2.6

[EternalBlack]

Whenever I try to install this plugin on a fresh/clean install for Craft CMS 3.2.6 I receive

Error
Class 'Craft\base\Plugin' not found

I have another system that has the plugin already installed for a while and is on the same Craft CMS version. Uninstalling it there and reinstalling it works just fine there.

This is what I could find inside the logs:

Fixed in 1.0.1. Thanks for reporting!
