I just installed Matlab 2020a. I also have Matlab 2014a on my computer as well. My problem is, 2020a starts without an issue and "ready" prompts at bottom left. But the moment I write a simple line of code, for example "a = 5" to the command window, it gets stuck in busy and never finishes execution. Is there a fix to this or do I have to reinstall 2020a from scratch?
