I have read on another thread that the error might be CPU related, the cpu on the AWS machine is Xeon Platinum 8124M.
When rendering on my local machine it works fine.

Thanks for the pointer; looking into it.

Best regards,

I have also tested with version 4.10.03, the error still happens

[ikomitov]

Yes, it's most certainly CPU-related. We are currently switching to LLVM 7 which knows how to target these Xeon processors so this bug will be fixed soon.

Best regards,
