Make sure your game is updated.
Check if those maps require "t4m" and "lan fixed.exe".
Try turning down your texture settings in the options menu before launching the map.

So i recently download 2 maps:
Minecraft village remastered 1.1,
Nuketown Remastered 1.2

But everytime i try to load up one of the maps,
it freezes and get a black screen.
And the only way i can close it is if i have the task manager opened
on my second or restart my computer.

If someone could help me out i'd really appreciate it!
thx
