Describe the bug
Gopls crashes when I interact with &cobra.Command{}. Specifically the cobra part, I wanted to use it to insert the import.
Steps to reproduce the behavior:
- Click on "cobra".
Screenshots or recordings
The log file is in hermes.zip. I seem to be able to reproduce it just by restarting gopls. It's possible I'm running a version of gopls built from one of my CLs but gopls version shows golang.org/x/tools/gopls v0.19.0-pre.2 so I think not.

Comment From: firelizzard18
The automated reporter didn't work. I think the log file is too big.
Comment From: firelizzard18
I ran sudo rm -rf ~/go/pkg (some stuff in there was owned by root, probably due to running a job with docker) and rebuilt gopls. It was crashing on one particular file and after this it stopped crashing for that file, so that may have been the issue.

Thanks. The salient portion of the log is this:
