pr_finish() error

[jennybc]

A new weird error with pr_finish() has arisen:

> pr_finish()
ℹ Finishing PR tidyverse/readr/#1537
✔ Switching back to default branch ("main").
✔ Pulling changes from "origin/main".
✔ Deleting local "bastistician-check_encoding" branch.
Run `rlang::last_trace()` to see where the error occurred.

I see this in .git/config which is presumably the problem (and I'm guessing is coming from the GitHub pull requests extension?):

[branch "bastistician-check_encoding"]
	github-pr-owner-number = "tidyverse#readr#1537"
	github-pr-owner-number = "tidyverse#readr#1537"
