> QuickOPC does not support them, so you won't be able to read that node after the fix anyway.
I understand it. The main thing for me is to avoid an error. The fact is that we made a program with which users can try to read any tag they wish. And the main thing for us is to exclude the program crash.

I was able to reproduce the problem. This appears to be a bug in QuickOPC 2019.2. Thank you for reporting it.
There will be a fix (a new build). Please be patient - it may take some days. I will make another post here when it is ready.
Note that the problem has to do with reading values of type ExpandedNodeId that contain non-zero server index. QuickOPC does not support them, so you won't be able to read that node after the fix anyway. The proper behavior is that a non-null .Exception appears in the corresponding element of the array returned from ReadMultiple or ReadMultipleValues.

On your PC, the error does not occur when reading the tag "ExpandedNodeId"?
