I will tell you the process of the problem. Please follow me.

hololens2 streaming suddenly stopped working.

I'm using this command for streaming from a packaged Windows executable

After seeing this page, I installed window mixed reality openxr app from the Microsoft store on the HoloLens device, and streaming worked again. However, there is a phenomenon in which the anchor is continuously loaded at the origin position.

My questions are,

1. Is it because I did not install window mixed reality openxr on the HoloLens that streaming did not work?
2. Can't use the hololens anchor while streaming on the new system?

3.How can i use local anchor again while remote streaming?
