Went to open up an older version of tizen studio that hasn't been used in a while and it would error out. Went out and installed the latest 3.6 version mac gui installer. Installs and opens fine.
If you try to open the package manager you get a "Failed to execute runnable (java.lang.NullPointerException) cause: null". I got around this by running the package manager from the command line: java -jar -XstartOnFirstThread PackageManagerV2.jar
This opened the package manager and i could install things normally.
Re-opened tizen studio and go to open the emulator manager and it tries to open and immeidtely closes without warning. Cannot find a solution for this. I added both tizen studio and package manager to the new catalina full disk access permission list and that did not help. I saw some other catalina posts but nothing seems to work. Default java version is set to 1.8.
