SA1135UsingDirectivesMustBeQualified threw an exception of type 'System.ArgumentNullException' with message 'Value cannot be null. (Parameter 'syntax')

.NET version: 9.0.1
Stylecop version: 1.2.0-beta.556

Error:
##[error]CSC(0,0): Error AD0001: Analyzer 'StyleCop.Analyzers.ReadabilityRules.SA1135UsingDirectivesMustBeQualified' threw an exception of type 'System.ArgumentNullException' with message 'Value cannot be null. (Parameter 'syntax')'.

Line that triggers it:
using RequestResponse = (int UpdateCount, int CreateCount);

so using directive that is an alias for a new tuple.
