I am able to reproduce this crash with the following two minimal scripts.
------------------------ x.vim ------------------------------
vim9script
import './y.vim' as server
export def Hover()
enddef
def AddServer()
var d: dict<any> = server.NewLspServer()
enddef
AddServer()
---------------------------------------------------------------
------------------------ y.vim ------------------------------
vim9script
def Hover(d: dict<any>): void
enddef
export def NewLspServer(): dict<any>
var d: dict<any> = {}
d->extend({hover: function('Hover', [d])})
return d
enddef
NewLspServer()
---------------------------------------------------------------
With the above two x.vim and y.vim scripts, if you source x.vim,
then Vim crashes.
