I was preparing a Blu-ray disk with DVD Architect (I think it's 7.0... About says: DVD Architect Build 100 Copyright (c) 2018). I've made .iso files from this same .dar file yesterday with no problems. All I did was change the "Set Disc Start" to the main menu and change one of the links so the videos would flow in the correct order. Twice now I've gotten "An error occurred while preparing compilation" and it's complaining about not being able to find file File_addr_map.map. See screenshot.

Did a DVD Architect file get corrupted? Do I need to reinstall DVD Architect?

I looked for the file manually and after changing File Explorer Options to show hidden files, folders, and drives, I could see that the ~bdmux12884 folder was not there, but it may have been deleted during cleanup.

I'm creating a single-layer Blu-ray disc image, which is about 24 GB and I've got 74.2 GB of free space on my SSD, so it shouldn't be a space issue.

Please help!

Thanks.
