igv: IGV won't start anymore on Mac

Hi, I was running IGV just fine until yesterday, when it started running away with CPU usage, and then after force quitting, it won’t launch again. I’ve tried deleting all the relevant files, reinstalling etc and to no avail. I’ve tried launching it with Java 14 as well as Java 11…

Here’s my error message: `WARN [2021-02-03T12:24:08,520] [Globals.java:135] [main] Development mode is enabled INFO [2021-02-03T12:24:08,536] [DirectoryManager.java:180] [main] IGV Directory: /Users//igv INFO [2021-02-03T12:24:09,657] [Main.java:205] [AWT-EventQueue-0] Startup IGV Version 2.9.0 02/01/2021 06:00 PM INFO [2021-02-03T12:24:09,675] [Main.java:206] [AWT-EventQueue-0] Java 11.0.9 (build 11.0.9+11) 2020-10-20 INFO [2021-02-03T12:24:09,676] [Main.java:209] [AWT-EventQueue-0] Java Vendor: Oracle Corporation https://openjdk.java.net/ INFO [2021-02-03T12:24:09,677] [Main.java:211] [AWT-EventQueue-0] JVM: OpenJDK 64-Bit Server VM
