How to reproduce

Place the OrcaSlicer.app in a path that contains characters that are special in URLs (e.g. ‘%’ or ‘#’, I place apps that are not installed from the App Store in “/Applications/#ThirdParty”).
Start OrcaSlicer
The home tab is empty

Actual results

OrcaSlicer fails to load the home page resource, the home page tab stays empty.

Expected results

The home tab should work.

Project file & Debug log uploads

not relevant.

Checklist of files to include

Log file
Project file

Anything else?

The problem are this line and that line that build a file:-URL by simply inserting the path to the resources directory without correctly encoding it.

The same problem exists here, here, and here.
