@devcsantos: As @Zheng-Li01 mentioned we couldn't repro the issue due to apostrophe in the path. However, the issue you are seeing seems similar to the one described in this VS Feedback ticket. We are investigating this issue. For time being the workaround I mentioned in the ticket should unblock you.
