Testing Ignition 8.3.0 Beta. I had to upgrade my Designer Launcher to 1.3.0 Beta-1 to access the 8.3 designer. However, I'm now unable to open any of my other 8.1.23 designers; I receive a "Launch client jar invalid" message. I ended up downgrading my designer, but this means I can no longer access…

Try closing the Designer Launcher first and then change the value to LENIENT
