I'm pretty confident that this crash always happens when new resources are being added, though am only 90% sure. No crash log is generated, though, and apart from "Failed to create BitmapFrame" nothing appears in the error log either.
So, attached is the logos4indexer.log file which contains the following error:
LogosResourceCore Exception (WER status is 2) creating resource at 'C:\Users\Mark Barnes\AppData\Local\Logos4\Data\5amtqjih.p4f\ResourceManager\Resources\21b5fd1d082a4157a3dff3a21fda9d73.lbspbb' with expected resource ID '(null)' and version '(null)': Operation is not valid due to the current state of the object.
That file does not exist.
According to my PersonalBookManager.db (also attached) the file relates to a PBB called "One Volume Commentaries (Print Editions)". This file does exist in the Personal Books tool. It does not, however, exist in my library.
I guess I could rebuild the book, but I'll hold off for the time being, in case you want me to do some more diagnostics.
