Can please add a simple test file with steps to reproduce ? Issue is possibly related to rigify addon so changing the tag

Think the keyframes are actually inserted correctly.

Rigify has a problem though [which was still possible in 2.92, only 2.93 onwards has this problem]:

In the attached file, the properties in rig_ui.py are defined using the old = assignment, but looking at the git blame of the code that generates that code, it has been kept up to date immediately with Blender 2.8, and changed to the new : annotation syntax.

So this means your rig was generated with a version of Rigify and Blender that are more than 3 years old, and that's why it's no longer compatible with current Blender.

The ideal solution here is to find the metarig that generated this rig, and re-generate it with the current Rigify. If that's not available because the rig's author has made the huge mistake of discarding the metarig (which should never ever be done) then your best bet is to simply go into rig_ui.py and replace the = signs in the operator class definitions with : signs, as per Blender 2.80 Python API requirements.

Thanks for the report, but there's no bug here, so closing. Hope the above info will help with the problem though.
