Latest snapshot reads "1.14.4" instead of the new "19w34a". I've restarted the launcher multiple times but it didn't help. Manually downloading it and putting it into the versions folder won't work either.
My image of it won't upload here so I've uploaded it to Reddit instead

Killing some leftover java processes running in the background from previous Minecraft sessions fixed it (apparently closing Minecraft still leaves the java application running in the background?)
When doing that, did you close Minecraft itself, and all windows belonging to the launcher as well?
