Are you on Minecraft Bedrock Edition? Because I downloaded it and it worked fine. If you are on Bedrock Edition, then it won't work. The download is for Java Edition.
If you are trying to play it on bedrock, you will have to convert it using some third party software like 'MCC ToolChest' or som other, but if you are playing on java you may have corrupted the download somehow.
