Unfortunately you’ll have to change debugger format unless you’re willing to upgrade to the latest VS2015 (Update 2 RC 3 or whatever) or maybe upgrading to cocos2d-x 3.11 (this may not fix it, however, but I believe the issue is related to the massive number of Action class hierarchy that blows up the database and I think a recent pull request may fix the issue now that it uses templates instead, but probably not).
You should not get this error if you change to /Z7 debugging instead of the full PDB debug setting. There’s a similar topic on here I’ll find and edit this post with the link.
Edit: link -> Compile takes too long in Visual Studio 2013
