Unable to run from Run | Debug buttons

rust-analyzer version: 0.402095-linux-x64/server/rust-analyzer

rustc version: 1.80.1

editor or extension: VS Code

relevant settings: (eg. client settings, or environment variables like CARGO, RUSTC, RUSTUP_HOME or CARGO_HOME)

I've been working with Rust-Analyzer for a while but I took a break from my Rust project for about a month. I came back and ran updates, but now it won't run code or tests.

I can run code from the integrated terminal and VSCode directly (F5, cargo run/test), but when trying to run any code from the Run | Debug buttons above Tests or Main, it fails.

On running it gives me the error: "Terminal process failed to launch: Path to shell executable "cargo" does not exist."

Trying to run debug gives me an additional Error:
"Cargo invocation has failed: Error: could not launch cargo: Error: spawn cargo ENOENT."

Reproduce the failure from the Run | Debug buttons above Tests or Main, then compare it with F5 and integrated-terminal cargo run/test, which work according to the report. Trace the launch path that invokes cargo and verify that these buttons can find and start cargo rather than treating it as a shell executable.
