Construct 2 R229 error on the new UI update!

I just updated to Construct 2 R229, at first glance I liked the new design of the update until I went to the event sheet and clicked add action, it lags and after I select an object in the dialog it shows the error with a title of "CHECK FAILURE" and C2 crashes. And the error dialog sometimes shows a message about a memory leak. I can't use Construct 2 anymore without crashing.

I also noticed that it only happens on big projects (with hundred of objects) but not on templates. I also tried different types of Icon Mode and still no good. I also get a sluggish performance depending on the number of object in my project.

I'll post a before & after video after I am finished.

Might be helpful:

Ashley , what happened to the new update?

Please file a bug report following all the guidelines, there's not much we can do otherwise. Also as ever including the contents of any error messages is essential.

Ashley - Here is a video record I made of the errors , please kindly look at it:

I never had problems with R228 but with R229, you'll understand once you watch the video.

Please, post this all to a bug report following all the guidelines. Otherwise the thread will most likely be lost and forgotten.

Okay, i"ll do that.

Edit: I've reported the topic to the mods so that it will be moved to the bug section to avoid duplication and i'll just insert the necessary details necessary for a bug report later on.

No, please don't do that, it just gets confusing. It's fine to start a new thread.
