Thanks for the report @steven-meadows
Can you please share the output of the following two commands?
We need to know the go version and the go version used in building your gopls.

$ go version
$ go version -m <path_to_gopls>

And, transferring this issue to gopls issue tracker for followup.

[stamblerre]

/cc @findleyr, though of course we need the Go version to make progress here

[findleyr]

I believe this is #39634, crash #12, which is fixed at tip.
