Running tests from a project, I see a lot of failures with "unable to open database" errors. Tracing through decompiled code via rider, the problem seems to be in SQLiteConnection.MapUriPath, where a uri like is being erroneously translated into and later on that is expanded to by SQLiteConnection.ExpandFileName, which, of course, cannot be opened.

I would have raised a PR with a code fix, but I'm not sure how to do so considering the download source options from mention using Fossil or provide snapshot code. If this project were on GitHub (or something similar with a pull request workflow), I'd have provided a fix. Sorry.
