Left Click Crashes Unreal Engine 4.9

So I loaded up my project in 4.9 for the first time. But it seems that when I Left Click UE4.9 instantly crashes.

I have traced it down to the last part of my Left Click BP which is set collision Enabled. If I remove this everything happens as normal / No crash but obviously the collision isn’t enabled

Hi Kuuwahi,

Did you submit the crash report as well? If not, please reproduce the crash and make sure to submit it.

Is this reproducible in a new project or just your current one?

Please post your Crash Logs, Dmp file, and Dxdiag (system specs).

I have noticed that this doesn’t happen if I set the Collision Enabled - New Type No Collision. But anything else from the drop down list causes a crash.

Only Unreal Engine Crashes not my Machine.

I have submitted the report.

This does not happen with the previous versions (4.8.3)

I have attached my DXDiag

Hmm, so far this is the only report of this exact crash that we’ve had. I noticed that your Graphics Card driver is out of date, could you try updating and see if you still get the crash?

Hi Kuuwahi,

We haven’t heard back from you in a few days, so we are marking this post as resolved for tracking purposes. If you’re still experiencing this issue, please feel free to post back here with additional information.

Cheers,

TJ

Hello,

I deleted the entire collision and blueprints and started again and I didn’t experience this issue again.

The problem is no longer existent since remaking it.

Cheers.
