I believe bash loads (some of) them automatically. Therefore, bash
knows the parameters --noprofile and --norc.

It would be very helpful for investigation, if you could move these
remote files away temporarily, and check whether the error persists.

If it is reproducible with bash 5.0, I would like to add a not to the
Tramp manuals. At least.

Thanks for your support in testing.
