Starting Xojo IDE loading PDF Web example

Feedback Case Number:
I just installed Xojo 2021 R1.1 and installed it o my Linux Mint 19.2 64-Bit via DEB.
Started the IDE and tried to load the PDF-Web example in the Example-Selection.
When loading starts the whole IDE vanishes and nothing happens…no reaction.

Any Idea ?

Example was EE-WEB example project. Other projects (database for example) loaded correctly…

You may run Xojo via Terminal app to see log messages.
