Processing-java 3.5.3 won't launch on Mac OS X 10.15

Processing
1

EDIT: HAHAHA I don’t know what went wrong with my code but it turns out that the java launcher was working properly and I just messed up in my code somewhere.

I was working on a sketch with Processing this morning and it was working fine. But when I put my computer to sleep and turned it on a few minutes later to resume my work, my sketch suddenly stopped launching properly. The application does not respond, and it prints the following message in the Processing console:

It may be an issue with MacOS Catalina, but I’m not sure and any help would be appreciated because I need Processing to do projects for school.
Thanks!
