Thanks @ankugarg for opening this issue and providing logs, could you please provide a little more context around what you were trying to do when this issue occurred--repro steps, gifs and screen shots are all great!

[amitoverflow-ui]

@SydneyhSmith sorry for not providing information earlier. Have attached gif. Please have a look at it.

Steps to reproduce:

1. Apply breakpoint and start debugging via pressing F5
2. When debugger stop at breakpoint, press F5 again

Please let me know if more info is required.

@ankugarg thanks that information is really helpful, does the crash happen just after the GIF ends?

[amitoverflow-ui]

@SydneyhSmith - Yes.
I have uploaded the video to give more clarity on the issue - https://www.youtube.com/watch?v=8plhDp3ZCvM

Thanks @ankugarg really appreciate you taking the time to upload a video, really helps us better understand the issue.
Could you please also attach the payload logs, instructions for how to do that are here

[amitoverflow-ui]

@SydneyhSmith have attached the logs but there is no error PayloadLogs.log

Although debugger did crash on UI

Ok this looks like a good old bug in the debugger to do with the current pipeline thread issues. Working on a fix currently, but it's large and complex -- will take several weeks to implement
