Ignition 8.1.18. I am getting an occasional error on clients where vision will freeze during a login. We are using a custom login screen. After 30 seconds, an error box pops up. The initial error appears to cause an infinite exception loop, building up the stack trace for each exception until the stack overflows. The stack trace for the final exception is 550 lines long. The full error message looks like this.
