I just updated my unity project to 2020.1.0a23 and started getting these errors whenever i go into play mode with my project.

 

The "a" in "Unity 2020.1.0a23" means it's an alpha build. Alpha builds are early, unfinished versions that are not stable- so you don't want to use that version. In general, avoid any version that has an "a" or "b" in the release number.

 

If you're using an unfinished alpha test version of Unity on purpose, you should post issues like this in its dedicated forum. Otherwise what @kdgalla said.
