This might not be a problem with strawberry, but some other library, but I hope you can still help.

I'm trying to install the gstreamer plugin following the instructions in the wiki:
https://wiki.strawberrymusicplayer.org/wiki/Installing_GStreamer_Spotify_plugin

unfortunately this does not work for me.
When I try to use ninja, I get following error:

SyntaxError: f-string: expecting '}'
FAILED: libgstspotify.so 
env PKG_CONFIG=/usr/bin/pkg-config 'RUSTC=rustc -C linker=cc' /usr/bin/python3 /home/user/path/gst-plugins-rs/cargo_wrapper.py build /home/user/path/gst-plugins-rs/build /home/user/path/gst-plugins-rs /home/user/path/gst-plugins-rs/build release /usr/local lib/x86_64-linux-gnu --packages gst-plugin-spotify --depfile gst-plugins-rs.dep --lib-suffixes so --disable-doc
ninja: build stopped: subcommand failed.

Any idea how to fix this?
Or is there some prebuild version of the gstreamer plugin I can use?
