Managed to reduce to a fairly small sample:
@startuml
!define AWSPuml https://raw.githubusercontent.com/awslabs/aws-icons-for-plantuml/v11.1/dist
!include AWSPuml/AWSCommon.puml
Alice -> Bob
note right
<code>
Some text
</code>
end note
@enduml
If remove the include AWSPuml/AWSCommon.puml it works.
Or if remove the <code></code> lines it also works
Cant see anything obvious in that include to cause issues.
