Question 1: The exception is displayed in the running state, which means that the system prompts the client to exit abnormally, disconnect abnormally or run incorrectly. These errors can be solved by "clearing exceptions". After registering with admin, there is a "Clear Exception Task" under the view, which can be cleared after being selected.

Question 2: The established 002 A/C set exists, but the user name you used can't see the 002 A/C set, because you didn't give this user name the right to use the 002 A/C set. There is a "permission" function under the permission menu. After setting permissions in 002 A/C set, you can see your user name. Good luck.
