I'm having the same exact issue with a very minimal example (repro.zip) that sets up a simple python binary. No custom .bazelrc at all.
Running:
bazel run --enable_bzlmod --lockfile_mode=update //:main
Results in the creation of a MODULE.bazel.lock file that contains an empty JSON object:
The next attempt to run the bazel command above results in the following crash:
FATAL: bazel crashed due to an internal error. Printing stack trace:
