I had a similar issue. NetBeans 17, JDK 17 (MS Hotspot Windows 10 64 Bit).

Turns out that a XSD File was incorrectly encoded. It was created by jaxb2-maven-plugin without encoding property. The file could not be opened in NetBeans at all (there was an encoding warning dialog). It was also stored in my SVN Repository. When I opened the projekt, NetBeans hangs in a neverending loop "Scanning Background Projects". I identified the problem project by quickly clicking on the details of the background process. After deleting the file or closing the project, the problem was gone.
Issue Impact: I spent several hours to solve the problem. May be other problems I had this week were also related to this issue (Java files did not compile on save by nb-javac). The problem also may cause overheating of your computer because it requires significant CPU resources and you may not notice it.
