Edit: Sorry, looked at wrong version in the mod table when writing the title and can’t edit it. Affected is version 0.3.6
Steps to reproduce:

• Start a new map on Factorio 1.1.53 (older 1.1 versions are likely the same)
• Open the Tips&Tricks menu
• Try to start any interactive lesson, like moving stacks or the train tutorial
• This error message pops up instead of the expected tutorial map:
