*Crash*drag blueprint from content draw to new First person scene

Development Programming & Scripting Blueprint

Hi, I have a new ‘first person’ template open. When I try and drag a blueprint from content draw it crashes every time. The blueprint has Blueprint class/actor with a static mesh.

Latest graphics driver installed running UE5.2 on windows 10.

If I do the same but instead drag to a Architecture/blank scene instead of ‘Games/blank’ it doesn’t crash.

Earlier I had issues with importing datasmith into Game templates. It crashed in Game but fine with Architecture.

Is this a known bug in 5.2 or am I doing something wrong?
Thanks

I just tried to repro on my 5.2: a game > first person template.
I created a blueprint from actor and added a mesh in it then drop in viewport and it worked. Same with a blueprint created from static mesh actor parent class.

Can we get the log from a crashed session?

Hi, Thanks for your help.

Just to add. I have visual studio 2019 installed because of a 3dconnection (3dmouse) plugin. VS 2019 was recommended for the plugin compile. I have NET and C++ installed for VS. My UE5.2 is installed on my D drive. VS is installed on my C drive. I dont know if that matters.

Tried UE5.1 and I am getting the same crash as 5.2
Tried turning off Antivirus and firewall but still crashing.
Scene files on I drive
UE5.1 build on D drive
UE5.2 build on D drive

Error shows - check(IsRunningCommandlet());
