Regression: output from LyX 2.4.0 RC3 won't compile (worked with LyX 2.3.7)

[Adrian Kieß]

Dear LyX list and LyX developers,

the problem with my document only occurs when I try to compile the
whole document with two depending files, a .bib and a .txt file.

I shortened the document to a minimum, but then the LyX document can
compile with:

 % lyx --version
LyX 2.4.0~RC3 (2024-02-09)

If it is possible, I can attach all three files: the complete LyX
document in for LyX version 2.4 (and 2.3) format, the .bib file and
a .txt file to my next reply.

Thank you very much,

Adrian Kieß
