Cannot get WallPaper name or File Path. Flash back

phone: 14 pro max
IOS:16.6
airwall-v:1.5

May I ask, whether the wallpaper can be modified successfully is related to the car and carplay version?
I have a friend who has the same IOS version as me, but he can't get the "file path". I've tried reinstalling, clearing the cache, changing the wallpaper on the car. There are also some friends with different ios versions still "please wait" and then flash back.
Finally, can you explain the underlying logic of AirWall replacement wallpaper?

There are still a lot of people who have successfully changed the wallpaper, and we are very happy.
