Obs 29.1.3 with PTZ Controls crashes

[corys70155]

Obs 29.1.3 with PTZ Controls crashes every time I try to put in a camera control. I am using a Waveshare rs-485 USB adaptor to connect with the cameras. These cameras do not have an IP address. They use a com port and a Device ID but when you hit "Apply" OBS just shuts down. Is there a solution for this or should I look for another way to connect?

I hope it helps! QtSerialPort-6.4.3.0

I had this problem too. GustavoAntonny pointed me in the right direction, however the version of OBS I was using was built against qt 6.5.3 so I need to find the corresponding version of the serial port dll (i.e. 6.5.3) and then it worked!
