问题 I am having lots of issues with windows version of Tizen studio such as emulator manager, control panel doesn't open. So I tried mac version but installing it on startup it could not open package manager with "Failed to execute runnable (java.lang.NullPointerException) cause: null" error, despite having valid JDK 11 and latest installer 3.6.

问题 I see there is a question here in SO, but the proposed answer (deleting .metadata folder) does not work for my case. Here is what I did: First, I had a certificate file (once I generated a certificate signing request file, and was given a certificate file for that).
