Pandoc fails to render markdown with image: "! Missing endcsname inserted." - macos

Question

I am having trouble rendering a .md-file with since I inserted an image. Before everything worked quite well.
My configuration
MacBook Air / MacOS 12.5
multiple markdown files for each chapter: 1_einleitung.md / 2_theorie.md / ...
there is a short yaml-block that references the bibliography file within the same folder: bib.bib.
I use a special LUA filter (pangb4e) for numbered examples and interlinear glossing
a metadata.yml ➞ find the yaml code below.
a Make-file ➞ find the makefile code below
the image is stored in images/danes1.png (I even tried to use the entire path instead of the relative one)
2_theorie.md

bibliography: [bib.bib]

The error output
Currently, I do my writing within the 2_theorie.md and run the command make 2_theorie to produce a pdf. I just inserted an image in 2_theorie.md and a get the following error:
san#MacBook-Air Doktorarbeit % make 2_theorie
pandoc 2_theorie.md -o 2_theorie.pdf \
--metadata-file=metadata.yml \
--number-sections \
--strip-comments \
--filter pandoc-crossref \
--citeproc \
--lua-filter addons/pangb4e.lua \
Error producing PDF.
! Missing endcsname inserted.

When I delete the image, the code runs as usual but I need to be able to use images in my work.
If you need more information, please let me know!
Thank you!

I found a solution to my problem myself here: https://tex.stackexchange.com/questions/448314/not-able-to-use-images-if-i-call-gb4e-sty
The problem was the package gb4e. I disabled the a feature of the package right after loading it and panda worked just fine
Edits in the metadata.yml

header-includes:
- \usepackage{gb4e}
