Node-Red crashes using OpcUa-Server node

I just installed the SD card using the example image: 109741799_RT_IOT2050_Example_Image_RT_V1.3.1_PNDriver_2.3.zip. As a result, I have Node-RED version v2.2.2 and Node.js version v12.22.12. The system functions perfectly with all the development we have done. However, we are encountering a significant issue when serving data via OPC UA. Node-RED crashes every time I add an OpcUa-Server node from the node-red-contrib-opcua library 0.2.262. I have tested several examples found on this forum and other websites, but the behavior remains the same: Node-RED crashes. Any help or suggestions to resolve this issue would be greatly appreciated.

It mentions that it cannot find the namespace for certain nodesets (line 80). Jul 12 11:50:57 iot2050-debian node-red[816]: 12 Jul 11:50:57 - [error] Error: Invalid Extension Object on nodeId =ns=0;i=17634 Please make sure that all XML files are correct and accessible. BR

A remote diagnosis is somewhat difficult here, but if you would like to contact me via DM and send me your node-red flow. We can take a look at it.
