Blank page after installing and login to 12.0

I also have the exact same issue, same error [Uncaught (in promise) TypeError: Cannot read property 'GetAllMetadataDates' of undefined]

Any hint from the folks on this thread that found the fix?

Thanks!

I finally fixed my issue. I am not an Aras "regular" and missed the very important details on which .Net & Core frameworks to install in the installation document. You MUST, very closely follow the links and description for the install machine. I had to try a number of times before finally getting it just right.

I have checked all Configuration and prerequisite. 

And it is similar with Aras installation guide.
