UE4 crashes frequently during work with blueprints

Hello guys,

while working with blueprints in UE4 version 4.14., the program crashes frequently. It is new for me to work with this program and I would really appreciate your help with the following error:

Fatal error: [File:D:\Build\++UE4+Release-4.14+Compile\Sync\Engine\Source\Runtime\Windows\D3D11RHI\Private\D3D11Util.cpp] [Line: 176]

Please help! Thank you.

It was known bug and should be fixed in 4.14.3. What version Are You using?

This thread may be useful as well:

We have a JIRA ticket for this particular callstack here: Unreal Engine Issues and Bug Tracker (UE-40807)

Luckily we have reproduced this particular crash internally and we are currently investigating the cause. You may track the JIRA while we update its status.

We still haven’t been able to reproduce the two other (Error: 0x887A0006 - ‘HUNG’) crash issues that most other users are getting.

You may certainly try the proposed workarounds in the AnswerHub linked above. I can’t guarentee that it will solve your issue though.

Also, keep in mind that a fix may not be implemented quickly for this crash we are still gathering information.
