EKF3 Failsafe problem

After last weeks mowing sucess I have now suddenly have no reverse and cannot run a mission.
I did bump into a gate post (not particularly hard) running a simple test mission to get me from one paddock to another.
I moved the waypoint to correct this, uploaded the new mission and went to run it but it would not initiate.
None of the modes are working like Circle and RTL, however it will work in Acro but still with no reverse.
The rover will go forwards no problem and it will skid steer no problem.
The telemetry is working, it boots up fine, I’m getting RTK Fixed on the GPS so really not sure what could be causing the problem.
I have had a look at the bin file but not really experienced enough to interogate it.
I did see that RCIN is getting the reverse command but RCOUT is not going below 1500 on one of the channels.
The link to the bin file : https://www.dropbox.com/scl/fi/vnnp0iovjq35mq1tby779/00000001.BIN?rlkey=zx3qqqmy933309gr88xvz0p28&st=579hc5l8&dl=0
Again, any help would be much appreciated.

Update on the problem
After a while of rebooting several times the auto modes started working but still no reverse.
I ended up recalibrating the radio and bingo, reverse came back.
Everything is working fine again.
Still no idea why it needed that.

your upload is not working for me
It asked me to register on dropbox, which I don’t like to do?
What kind of ESC are you using?

Juergen, Hi,

I also do not like using dropbox so understand why you were unable to check the .bin file.
There are two speed controlers, one for each channel. They are a British made controller from 4QD. The model is the Pro 160 which can be found here: Pro-160: 12V - 84V, 200A, programmable. - 4QD - Electric Motor Control

Your dropbox link shows to me that the file format is not direct supported and when I click download, dropbox asked me to register.
As I don’t want to register on theis service I am not able to download and open your file.
But I have seen that your problem was solved, so no further need
