I'm using Openstudio version 1.8.5, after simulating with package top roof, I try to delete this system to swich to VRF, deleting airside works well, with hot water loop, Openstudio freeze when I click delete red button (x), It might be a bug, please check.

Would you mind providing the model through drop box or equivalent? We are working on the final bug fixes for our upcoming 1.9.0 release so I am keenly interested in isolating and resolving this quickly.

Update - You might not need to provide a model because I think I have reproduced this one. If you have a default constructed "Packaged Rooftop VAV with Reheat" and remove the hot water plant first, before removing the air system, OS seems to get hung in an infinite loop.

I am also getting this error where OpenStudio 1.8.5 freezes after trying to delete a hot water loop. I have to force the program to close and restart. I tried deleting all the other airloops and zone equipment before the hot water loop, but it still crashed.

This has been fixed in the OS 1.9.0 release candidate, so hopefully OS 1.9.0 will not longer have this problem.

I have isolated and fixed an issue that I believe is your issue. Without seeing your model it is hard for me to know for sure. I think we are going to issue a 1.9.0 release candidate soon which I will encourage you to try out to double check that this is squashed. It was certainly a regression in 1.8.5 iteration package and a serious one at that. Definitely not something we want rolling out in a major 1.9.0 release.
