Dafny LanguageServer collapses #86

This has happened multiple times, with no apparent cause since it happens as I am modifying code. It has happened with automatic verification onchange and onsave.

Note that I have redacted the path when copying the error message to here, but it is to a different .dfy file in the same folder as the file I was working on.
