References -- TeX capacity exceeded

[Eckhard Höffner]

Hello,

Even though it's not an actual LyX problem, I hope someone can help.
I am using lyx 2.3.7 / debian testing. It has just updated texlive; 
LuaHBTeX, Version 1.17.0 (TeX Live 2023/Debian) (format=lualatex 2023.9.5)

In my opinion, it's the references, because if I delete all references, 
the error doesn't appear. The log file is over 100 kb so I won't send it 
here. But there is no error message in there, except for the one about 
the TeX capacity.

The abort starts with the first \label{mark}
Does anyone know why that is. When I use the LyX tutorial, which also 
includes marks and links, the error doesn't come.

Class scrbook Warning: \float at addtolists detected!
(scrbook) Implementation of \float at addtolist became
(scrbook) deprecated in KOMA-Script v3.01 2008/11/14 and
(scrbook) has been replaced by several more flexible
(scrbook) features of package `tocbasic`.
(scrbook) Since Version 3.12 support for deprecated
(scrbook) \float at addtolist interface has been
(scrbook) restricted to only some of the KOMA-Script
(scrbook) features and been removed from others.
(scrbook) Loading of package `scrhack' may help to
(scrbook) avoid this warning, if you are using a
(scrbook) a package that still implements the
(scrbook) deprecated \float at addtolist interface.
