New rust version crashes temper

Stacktrace

thread 'tokio-runtime-worker' panicked at library/core/src/panicking.rs:219:5:
unsafe precondition(s) violated: slice::get_unchecked requires that the index is within the slice
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
thread caused non-unwinding panic. aborting.

This happened to me with rustc 1.80.1 (3f5fd8dd4 2024-08-06)
Downgrading to rustc 1.73.0 (cc66ad468 2023-10-03) fixed the problem.
