General Discussion is not a support forum. As you are using the 2019.3 alpha, you should ask in the alpha forum: https://forum.unity.com/forums/2019-3-alpha.337/
Using alpha version, getting mysterious errors and asking is it normal? Aside from the improper thread title and posting in the incorrect forum section what did you expect your poll to do to help you?
Yes. It's normal for the alpha (these have an "a" in their name) and beta releases (these have a "b" in their name) to have these problems. If you don't want to deal with them you need to download the final releases (these have an "f" in their name).
