Too many parameterized tests results in mismatched UUIDs error

[rzhao271]

Testing #21494

1. Run through part of the TPI (at least the setup and running some tests)
2. Take a 5 minute break
3. Come back and try running the tests again
4. 🐛 See the following

2023-06-27 09:27:47.791 [error] On data received: Error occurred because the payload UUID is not recognized

After reloading the window, the error still occurs, and the test view goes back to the welcome view with the Configure Python Tests button.

Actually, it might be because I set the parameterized test to go from 1 to 100k instead of 1 to 10k and then tried refreshing again

Edit: Confirmed. 1 to 1k is fine. 1 to 10k results in some logs containing that error. 1 to 100k results in many logs containing that error.

This error was in the python output panel right? Currently unable to reproduce but will investigate further.

still unable to repo- going to close but can re-open if the issue reappears. Thanks

Discovered the root cause as discussed in this issue #21599. It is a problem with run or discovery taking to long and the UUID getting deleted prematurely.
