Hi, when you use the Beta version it is getting old. More than 1000 bug fixes since Beta are in the latest build. Check > https://builder.blender.org/download/.
You can use both versions at the same time.
If you have the same problem report it as bug over Blender Help menu.
Your system specs, Blender version and crash report are copy in the report form automatically. Very helpful for the developer.
I love Eevee and 2.8 in general, but I’m also having it just close out completely every few minutes.
It’s with an asset made in 2.6x with diffuse and glossy materials. It always crashes during animation where the central object is spinning and the camera moves out away from it.
