Mobile data is not working

Unfortunately Mobile data is not working for me on cheeseburger. I wiped my device completely. Then I flashed OxygenOS 10.0.1 and then the official build.

The following data can be found in the log:

The device actually shows me "Mobile data 4G" when I pull down the status bar. But there is no connection
