After updating to v4.3.4 I’m having problems with Unity frequently freezing in play mode.
For example: I have a camera script that would previously cause null reference errors when its follow target was deleted inappropriately, now Unity just freezes when it happens and I have to close it with task manager.
I can’t be 100% certain it is the null reference that causes it as Unity locks up before displaying any errors, but it happens consistently with any script in a situation that would normally cause null references errors.
This has made debugging very difficult.
What I’ve already tried based on other posts:
Disconnecting my second monitor.
Changing external IDE from VS2012 to MD.
Deleting everything but my asset and solution files.
The camera example was done on purpose to narrow down the cause of the freezes.
As far as I can tell this problem occurs with any kind of null reference error and it is very hard to fix the unintentional null references when Unity freezes before displaying the error message. Not mention how annoying and impractical it is to have to restart Unity constantly.
Outside of infinite while loops I never had these kind of freezes before upgrading to 4.3.4.
I’m having the same problem.
Everytime when there was a null reference exception during execution, Unity will freeze when I stop / pause the execution.
It does not seem to matter what cause the Null Reference Error has.
It might have started after I used the debugger in Visual Studio. Elsewhere it was proposed to clear temp and library folders for the project. But that does not help in my case.
This makes development very tedious and finding bugs almost impossible, as I cannot scroll or read the error log after an error occured.
