It looks like the executable you are using to run tests doesn't support the --show-output flag (which is provided by rust-analyzer).
rustaceanvim will use cargo-nextest if you have it installed.
You can try disabling that by setting vim.g.rustaceanvim.tools.enable_nextest = false.
If that fixes it, then it's probably a bug in rustaceanvim, and the command should probably be sanitised for cargo-nextest.
