Divergence detected in AMG solver and floating point exception in ANSYS Fluent

I am trying to quantify the heat exchange of an empty aluminium box in the high atmosphere (25 000 m)

But I keep getting an error message (see image)
I have tried this command in the Fluent console:
/mesh/repair-improve/improve-quality

It happens right away during the calculation
I don't have a dynamic mesh
My skewness seems big, but I don't know how to improve this.
Can you help me, I don't know what is happening.

Any advice or recommendation will be highly appreciated.
Thanks in advance
