Developing first app - issues

Hi Guys!

I'm new here and in the Garmin development world, but I have decent amount of experience, especially in java. Still, I could not resolve this problem I'm gonna describe below.

Environment

I have a completely fress installed Mac M1 with the latest Sonoma OS with oracle java 21 LTS. I followed the Garmin dev guide and downloaded the SDK manager and installed all the devices and first the 7.0.0.beta1 SDK.

Steps I did

  1. I created my first project as instructed, and I after I turned off my built-in firewall, the sample digital clock app started. Awesome.
  2. Then I thought I do some experience  with the samples from the SDK folder and since then nothing works. I tried to run one of the samples, it did not run. Ok, let's try again the sample I created. Same error: Unable to connect to the simulator.
  3. I downgraded to SDK 6.4.1, no success.Nothing runs.
  4. I downgraded to java 8, no success. I found out it doesn't even build, maybe because the SDK version different, so I switched back to the latest beta, which I created the sample with.
  5. After I cleared out the bin, it runs again.
  6. Let's try then the sample from the SDK dir. Not working.
  7. Let's try again my sample (without any SDK or java change), not working again.

So I stopped trying at this point and I'd like to ask you guys, what am I missing here? I see that there must be a matrix between the java version I use, the Garmin SDK is marked as default AND the app's API level it was generated, but I'm a bit lost now.

Thanks for the help!
