### How to reproduce

_No response_

### Did this work correctly in an earlier version?

No / Don't know

### Operating System

MacOS Ventura 13.1

### JDK

openjdk version "17.0.5" 2022-10-18 LTS OpenJDK Runtime Environment Zulu17.38+21-CA (build 17.0.5+8-LTS) OpenJDK 64-Bit Server VM Zulu17.38+21-CA (build 17.0.5+8-LTS, mixed mode, sharing)

### Apache NetBeans packaging

Apache NetBeans binary zip

### Anything else

Not sure how often this happened our project has always caused NetBeans some issues when opening.

I'm not sure if it's something in our project structure or in NetBeans handling of large multi-module projects, or both.

### Are you willing to submit a pull request?

Yes

### Code of Conduct

Yes

Start at org.netbeans.modules.maven.embedder.impl.OfflineConnector.newInstance in OfflineConnector.java:43 and trace the Maven project-loading path through MavenEmbedder.resolve and NbMavenProjectImpl. Reproduce the error while opening the reported large multi-module Maven project; done means opening it no longer produces OfflineOperationError.
