Other personal books remain accessible.
This troublesome resource is searchable and is able to build a concordance but crashes when trying to open it.
I don't see a crash in the log (there should be a separate VerbumCrash.txt and a VerbumError.log files). Which PB is it and what's specific about it?
Does simply rebuilding the PB solve the issue?
The Concordance crashes when you try to open that PB in it? Could you upload the PB docx file?
It looks like a crash might be happening when running a search (in the background, for a visual filter document). I suspect it's very likely to be the same underlying problem from this post, which will be fixed in 8.14: https://community.logos.com/forums/t/190989.aspx
