when I pressd the play button, once there is no internet, the editor would crash, and no error window shows. I go to the log folder to find the editor log, and the last line is : * Assertion at ..\mono\metadata\threads.c:1788, condition `internal` not met. I tried to reinstall the unity3d 2019 2.11f,and useless. I created a new project, and still crash when there is no internet. and if build the project, the exe file is working fine.
