Solid red light on DJI mini 2

I’ve recently passed my test and have used my drone a few times. I’m not great with computer stuff but learning and fill everything in successfully to go fly yet on my last trip it had a solid red light on and said navigation error so googled it and did as it said. I restarted app and it worked yet next day it happened again but this time would not fly at all. Can anyone shed any light on this issue please. It’s a DJI mini 2

Is there also an error code beside that message?

Did you or anybody else crash this drone?

It’s not been crashed but yes there is an error code

Could you share the error code?
