This seems to be a widespread problem with iPad Pros. I installed fine on my iPhone X, but get the same error as you on my 2018 iPad Pro 12.9. I did a google search and the same issue is being reported on numerous support blogs. Hopefully a new beta will be released to address the issue. In the interim, I deleted the downloaded update by going into the storage menu in settings, and will live with the initial beta.
I’m trying one more time - restored my iPad Pro 12.9 to iPadOS 13.1.2 (all backed up so I won’t lose anything) and just deleted and re-installed the beta profile
