When i try to open the gui of the architect table it opens and closes immediately after. (you can find this out by repeatedly clicking on it so the flickering becomes more visible)
Tested on two different computers, w/ and w/o optifine. Happens in all cases.

It only does this if there isn't a land marked area defined for the architect table to read. I believe this is intentional

oh i expected it to transform some map location into a blueprint but i have to place it next to a location marked by land marks, thanks
