Older Versions Not Starting

I bought Minecraft Java Edition because of all the features that Bedrock Edition doesn't have. One feature that I was excited about was playing older versions of the game. But unfortunately, I can't do so. Every single time I try to play an older version of the game, it says: Failed to download file, the file contents differ from what was expected. The latest versions work fine. It's just these older versions. I've already tried repairing the MCL, but it does nothing.
