Sketch not loading to Arduino with IDE 1.8.12 and Mac OS 10.15.4

I am having problems with Arduino IDE 1.8.12 not loading to an Arduino Uno. I have attached a log file with the error at the end. I have tried older revisions of the IDE and get the same error. It appears to be some type of Java error but unfortunately I do not quite understand what it means nor how to fix. In addition when I go tools-boards-board manager and try to update or install the Arduino AVR boards to 1.8.2 I get an error “java.lang.NullPointerException”. Any suggestions? Using Max OS Catalina 10.15.4.

Hi, I have a same problem with MacOS 10.15.4 and more because Arduino application don't even want anymore open... it's real problem for Apple

To wait for the resolve by Apple or Arduino
