composer dmg build in 10.36.1

[SFRANCIS004]

I tried to build a small *dmg in Composer 10.36.1 on Catalina and it did nothing; no errors or failure.  I erase and installed Catalina a second time and had the same issue.

Composer was given Full Disk Access in Security Prefs. I was able to build the *.dmg using 10.34.2.

What worked for me is setting the DMG Target Filesystem to APFS or HFS+ instead of Prompt in Composer Preferences (Using Composer version 10.37.2).
