Hi Lynx,
Today, I created a separate "user command" within TeXstudio, and it points to "/usr/local/ConTeXt_Standalone/context-linux-64/bin/mtxrun" This command generates the same log output as the example at https://gitlab.com/islandoftex/images/texlive/-/issues/30.
This is probably not the same issue, since the path "context-linux- 64/bin/mtxrun" suggests that that isn't a symlink. (Well, it is a symlink mtxrun => ./luametatex, but that email is about multi-level symlinks like /usr/bin/context => /usr/local/texlive/2023/bin/x86_64- linux/context => ./luametatex) To compile a document, you almost certainly want to use "context" instead of "mtxrun". So try changing the user command to "/usr/local/ConTeXt_Standalone/context-linux-64/bin/context". If that doesn't fix anything, run $ /usr/local/ConTeXt_Standalone/context-linux-64/bin/mtxrun --generate $ /usr/local/ConTeXt_Standalone/context-linux-64/bin/context --make and try again. If it still doesn't work, then what do you get when you run $ /usr/local/ConTeXt_Standalone/context-linux-64/bin/context --nofile -- Max
