[Bug] S2G hangs in loop with various exceptions

[Hefaistos68]

Describe the bug Set recording to "window" (chrome.exe), user interaction. Then start recording, switch to the previously selected chrome window, press F11, S2G error pops -> see sequence of error messages as screenshots. Anyway, the only way to get rid of S2G is killing it. I suspect that on exception it doesnt stop listening for user interactions, thus creating new exceptions with every key or mouse click.
