Currently We testing aximmetry SE and DE 2020.5 release and it seems to me that this release unstable at all and have a lot of UI problems So I think that this release is not recommended to use in production environment.
I think we will stick with 2020.4.1 until these problems fixed
Can you please help us with telling us what are the steps that cause the problem?
In the new version if there is a serious issue a window will pop up that offer you to create a so called "dump file". Were you able to see this window? If yes: can you please create a dump file and send us?
