I have tried running the application through GDB to print a backtrace, and here is what it prints:
$ gdb ./build/src/vala-language-server GNU gdb (GDB) 10.1 (gdb) run Starting program: /home/hiphish/Applications/lsp/vala-language-server/build/ src/vala-language-server [Thread debugging using libthread_db enabled] Using host libthread_db library "/gnu/store/fa6wj5bxkj5ll1d7292a70knmyl7a0cr- glibc-2.31/lib/libthread_db.so.1".

() To me it looks like even before the segmentation fault happens even before the main function has been called, and it happens in a system library. Is there a dependency I am missing? I still don't understand why the program only crashes if I compile it myself with dependencies from Guix, but not if I install the application itself through Guix.
