Sencha Architect "Unable to open your app.json file"

I've been trying to follow Sencha's basic tutorial on Sencha Architect with the Sencha Architect trial version, but I've been stuck on the step of the tutorial titled, "Save Your Project". I've been encountering this error in the Sencha Architect Logs every time I save my new projects:

As the error suggests, there was no "app.json" generated by Sencha Architect:

enter image description here

The "CMD Output Tab" also produces this output upon saving the Sencha Architect project:

[INF] Initializing empty workspace at C:\Users\marco\source\sencha-sandbox\Test2
[INF] Copying framework to C:\Users\marco\source\sencha-sandbox\Test2\ext
[INF] Added framework ext to workspace.json
[ERR] The specified string cannot be converted into a valid namespace identifier
Exception in thread "Thread-13"
com.sencha.exceptions.BasicException: com.sencha.exceptions.ExState: Invalid namespace : Test2
at com.sencha.tools.server.service.tasks.DispatchTask.execute(DispatchTask.java:55)
....

If it makes any difference, I am using the latest versions of Java JDK (17.0.1) and Ruby (3.0.2p107).

Here is a selection of some of the things I've tried to resolve the issue, none of which have worked:

What I have been able to do successfully is create and run a project through the Sencha CMD following the Sencha CMD tutorial, so I find it interesting that the Sencha CMD-generated project works perfectly fine, yet my Sencha Architect Trial version cannot create a functioning project.

Another problem with sencha cmd v7.8.0.59 might be the installed java version.

When running sencha cmd manually I got: void sun.misc.Unsafe.ensureClassInitialized(java.lang.Class)

System java is OpenJDK Runtime Environment (build 23+37)

Since the sencha cmd bash script is looking for a jre directory in the sencha cmd installation directory, I just made an symlink to Java 21 and it worked afterwards:

cd ~/bin/Sencha/Cmd/7.8.0.59
ln -s /usr/lib/jvm/java-21-openjdk jre

I got into contact with one of Sencha's engineers today, who helped me to resolve this:

When Sencha Architect (v4.2.9) installed with CMD, the CMD version (v7.3.0.19) that was automatically installed alongside Sencha Architect was causing this error.

To fix this version issue, within Sencha Architect, I had to go to menu at Edit > Preferences > Dependencies, and change the default "Custom Cmd Base Path" from

C:\Users\marco\bin\Sencha\Architect\Cmd

to the install location of the standalone Sencha CMD

C:\Users\marco\bin\Sencha\Cmd

After doing that, you re-launch Sencha Architect, and Sencha Architect will ask you to update Sencha CMD, which you proceed with. From there, it seems that all your future projects should be good to go without issue.
