My game crashes when I create a new world. Removing Capsule causes the crashes to cease. No crash report was created.

Thanks for reporting !
The crashlog says "Invalid resource path: ....\instances\Elgia\saves\Test World!\capsules\c-delmetainf-config_capsule_starters__starter_house_of_the_hidden_barrel-0.schematics"
I suspect the the schematic as starter file might cause the issue by including a dot (.) in the file name.
I'll soon publish a version of capsule with improved schematic support, I'll ping you at that time so you'll be able to try again.
In the meantime you should be able to work capsule properly by removing the .schematic starter and replacing it by a .nbt version. The nbt version probably already have been generated at saves\Test World!\capsules\c-delmetainf-config_capsule_starters__starter_house_of_the_hidden_barrel-0.schematics, so you can rename it and move it to config/capsule/starters instead of the .schematic version.

There is a related issue at #71
It might also be related to GDLauncher. Do you also use GDLauncher @DeleteMetaInf ?

Yes, I use GDLauncher.
