I'm on a Win 10 skylake box with 32Gb of ram.
I run dozens of other engines and haven't seen this type of issue before.
I tried closing down Arena and restarting, still the same results.

The problem is this

Code: Select all

setoption name EvalFile value 

Seems that you have changed this option from its default value default.nnue to the empty string which makes the engine crash.
