What do you mean?

I entered the 350 everytime from a cold and dark state.

In msfs2020, the flight plan in SimBrief has been imported into the OIS, but when the ‘Copy Flight Plan Request’ on the MCDU is pressed, it goes to the ‘Pending’ state and then returns to the ‘Copy Flight Plan Request’ state after a few seconds. There is no response. Even after a long wait (5-10 minutes), there is still no response. Re-entering the SimBrief ID and Navigraph does not help. I tried deleting all the living and clearing the WASM folder, but it still doesn't work. I've tried everything I can find in the community, including saving the ‘Enable Detailed Navigational Logging’ setting, but nothing works. How can I fix this issue?
