Sorry to revive an old issue but I have been struggling with a similar problem - RB 2026 freezes when I try to generate a RealTrack. In my case the issue started when I upgraded from BB 2022 to BB 2026.

I tried everything from reinstalling BB 2026 several times to updating all of the HW drivers on my PC but no luck.

What seems to have worked (and I hope permanently) is freeing up hard drive space on the drive where the file you are working on resides. For example, I have a hard drive dedicated to music called M: where all of my .SEQ files are saved. I freed up as much space as possible on drive M: and I’ve got about 70GB free space now.

After freeing up space, I am able to generate RealTracks.

As a precaution, I also moved my RBBackup folder to a different drive so as to preserve M: hard drive space. (see Options – Preferences – 3-File, “Save backups to a custom backup folder…”)

I can appreciate your frustration. Hopefully this helps.
