sometimes when resetting an input, vmix crashes and has to be restarted. The issue is not reproducible but happens - last time during a running show.
We have to reset the input of several reasons - mostly because the camera losts its wifi or LAN connection (by purpose or someone unplugged it and has to be reconnected.
The last thing we see before vmix closes is the overlay message in a framed box: "safe handle has been closed".
We had it so far only with rtsp inputs - but this is what we use mainly to get our Panasonic UE-150 + UN38 + CX350 cameras in.
It happened on different computers and different hardware but both Windows10.
Any idea where we can have a closer look to or even fix this problem?
Thank you very much - it feels quite uncomofortable not to know when the whole system will crash next time.

Thanks for reporting this.
This appears to be an issue that is new in the latest .NET Framework, or at least a change in behaviour.
We will include a workaround for this in the next update, but I think it is worth clarifying how the Stream input works with RTSP sources, as using Reset is
not ever really necessary.
Every 15 seconds, the Stream Input will check the status of the stream, if it has stalled (that is no video or audio any longer) it will automatically try to reconnect.
It will always keep trying to do this indefinitely.
This error occurs when trying to reset while it is in the middle of reconnecting the stream, but the camera is not available for some reason.
If you don't reset, then it will still keep retrying every 15 seconds on its own.

Thank you very much, we will not reset rtsp inputs manually anymore or at least wait for the next update to do so.
Is it really the same internal process when pushing the reset command manually compared to the automatic 15 second retry procedure to connect?
We had the impression that pushing "reset" helps better to reconnect than the automatic way.
