Trying to install Mullvad VPN on Manjaro ARM Laptop via yay and getting rust backtrace error

Please help me solve this issue! I have already uninstalled rust but that did not solve the problem... Here is the code: error: failed to run custom build command for libdbus-sys v0.2.1 Caused by: process didn't exit successfully: /home/flowet/.cache/yay/mullvad-vpn/src/mullvadvpn-app/target/release/build/libdbus-sys-2e5f442eec395f29/build-script-build (exit code: 101) --- stderr thread 'main' panicked at 'called Result::unwrap() on an Err value: Command { command: "\"pkg-config\" \"--libs\" \"--cflags\" \"dbus-1\" \"dbus-1 >= 1.6\"", cause: Os { code: 2, kind: NotFound, message: "No such file or directory" } }', /home/flowet/.cargo/registry/src/github.com-1ecc6299db9ec823/libdbus-sys-0.2.1/build.rs:6:70 note: run with RUST_BACKTRACE=1 environment variable to display a backtrace
