Could not parse reference-transaction-line

Description of the bug

I've been getting these error messages for a while now on one repository. The error appears on basically every command, just pasting the output from git sw here:

$ git sw master

Tried both git 2.44.1 and 2.46.0. This bug only occurs on 2.46.0

[chrisdoherty4]

Git 2.45.2 is also working.

MacOS 14.6.1 (Apple Silcon)
