SDKTool in SAM 2020-11-29 Mac distribution will not start

SDKTool.app (November 29, 2020) in the sam-osx-2020-11-29 distribution exits with a "Library not loaded: @rpath/ssc.dylib" error without starting.
SDKtool.app in the SDKTool.app bundle (SDKTool.app/Contents/MacOS/SDKtool.app) exits with slightly more information:
dyld: Library not loaded: @rpath/ssc.dylib
        Referenced from /Applications/NREL/SDKTool.app/Contents/MacOS/SDKtool
        Reason: image not found
zsh:  abort        /Applications/NREL/SDKTool.app/Contents/MacOS/SDKtool

This behavior persists in MacOS 11.0.1, 10.13.6 and 10.11.6
SDKtool.app (May 21, 2019) in the sam-osx-2018-11-11-r4 distribution operates properly (per documentation).

These instructions are for MacOS 11.0.1 Big Sur. For more about SDKtool, see sam.nrel.gov/software-development-kit-sdk.html .
 
1. Download SAM 2020.11.29 for Mac from sam.nrel.gov/download.html and open the sam-osx-2020-11-29.dmg disk image.



2. Open a Finder window, go to the Applications folder, and create a SAM_2020.11.29 folder.
 


3. To run SAM, right-click the SAM app and click Open.


 
4. To open SDKtool, right-click the SDKTool app, click Show Package Contents and navigate to MacOS folder.



5. Right-click the SDKtool app and click Open.


 
6. SDKtool opens with no SSC library loaded.


 
7. To load the SSC library, from the Finder Applications/SAM_2020.11.29 folder, right-click the SAM app, click Show Package Contents,  and navigate to the Frameworks folder.


 
8. Copy and paste the ssc.dylib from Frameworks folder to the SAM_2020.11.29 folder.


 
9. In SDKtool, click Choose SSC library at the top of the window, and choose ssc.dylib from the SAM_2020.11.29 folder.
 
10. The module browser should display a list of modules from the library.

I get the following exception (MacOS Big Sur 11.5.2) when I try to open the SDKTool. It opened it with terminal:

Hi Dan,

Did you follow Steve's step-by-step instructions above to load the the library file?

Best regards,
Paul.

Yessir, I did.
