Dear list members,

The below MWE runs fine and generates a usable PDF.

If I uncomment the second question block and run the MWE on a OS X system it generates an unusable PDF and a nearly empty log file:

I cannot reproduce the problem on a Windows system.

Can somebody on an OS X system check and confirm the issue?
What if you wipe the tuc file?

No message?

I can confirm the same problem on a Win64 problem. I get the same log file (with 2019.10.29 15:09 for the version and my file/directory names).

There is a console message that is, perhaps, meaningful:

This is LuaMetaTeX, Version 2.00.0
runtime error : input file 'virtual://block.question.' is not found, quitting
mtx-context     | fatal error: return code: 1
