Cannot open 1.15 snapshots

So whenever I try to open one of the snapshots of 1.15, this will give me a launcher error and i'm not sure if anyone else has this problem.

I have tried uninstalling the launcher and deleting all the data it had, when i reinstalled and try to click play, the same popup still occurs, thus making me unable to play any snapshots.

If I am unable to play a full release of 1.15 and cannot figure this out, I may not be able to play minecraft again.
