After upgrading to Linux Mint 20, I've been having trouble with the help function/documentation in Matlab 2019a. Here's an error that appears in the command window if I try to search "fft" in the help search bar. I have no idea where to start.
Exception in thread "AWT-EventQueue-0": java.lang.NullPointerException
