When attempting to add a new diagram by going to my project -> Diagrams, then right click and Add Diagram, I receive an exception, which prevents me from further usage: java.lang.IllegalArgumentException: Parameter file was not normalized.

AFAIK, this exception means that org.netbeans.modules.uml.project.ProjectUtil.findNetBeansProjectForModel passes a non-normalized file into FileUtil.toFileObject, which is not permitted. Should be IMO fixed in org.netbeans.modules.uml.project.ProjectUtil.
*** Issue 80894 has been marked as a duplicate of this issue. ***
What is an non-normalized file?
Any details if it's reproducible with later releases or new fresh installations?
also initial exception say about UpperCase first letter vs LowerCase, it may happens after file copying in some cases etc. feel free to reopen if reproducible for anybody otherwise can't be fixed.
