Hi therealalbaro, from the screenshot you posted above, it appears you have downloaded WireShare 6.0.1 with embedded Java 6. Therfore, it doesn't matter which Java version you have installed as WireShare will use the embedded JDK. I currently don't have a Big Sur machine to test on but I think the issue may be Big Sur not playing well with the embedded Java. Additionally, the embedded Java 6 version is 32bit which may also be an issue on Big Sur. Maybe you could try the WireShareOSX-v6.0.1.dmg which is compiled with Java 8 and has an embedded Java 8 64bit runtime and let us know your findings.
