This may just be an internet issue.
My friend cannot provide evidence, because he plays Minecraft on a different computer. You should definitely look into the issue though, because he found it.
I have that issue too! It's normal, and you need to go to whatever store you have to update Minecraft. It is 1.16.100, but it should be 1.16.200. After the update, you should be able to play.
