Failed to mutate `field` keyword.

[kudima03]

Describe the bug
Failed to mutate .NET 10 project with field keywords.

Logs
log-20251113.txt

Expected behavior
Mutation process ends up successfully.

Desktop (please complete the following information):

• OS: Windows 11
• Type of project: .NET 10 (Class Library)
• Framework Version: .NET 10
• Stryker Version: 4.8.1

Additional context
field keyword causes exception. Code without this keyword is being mutated correctly without exception. Probably Stryker misses field keyword mutation support.

This is due to Stryker not yet supporting Net 10. We have yet to release a Stryker version supporting Net 10.
Update: this is pending the release of Roslyn 5.0 (through Microsoft.Analysis.CSharp package). It is currently in preview.
I did a quick test with the preview version of said assembly: it supports the field keyword.
