Configuration resource is not supported

[smd100]

I'm using SEB 3.8.0 x64 and only one of my students (out of 125) gets this message.

The log file shows it seems to fail because there is no data parser to parse 'System.IO.FileStream'.

Here's the relevant part:

`2024-11-09 18:35:29.397 [06] - DEBUG: [BinaryParser] 'System.IO.FileStream' starting with '+' does not match the Binary format.

We've tried completely reinstalling SEB from scratch and checking that .NET runtime is installed - it is (v4.7.2).

How can we fix?

Thanks.
