I did some tests on HoloLens2Example and couldn't reproduce your issue. When the anchor is loaded, the environment information saved in the anchor will be matched with the current environment to find the correct position. So, if the device is in some extreme environments, it will affect subsequent operations. Please refer to HoloLens environment considerations | Microsoft Learn to learn more. You can try testing in different real-world environments.
If you can reproduce this issue constantly, please provide your development environment and detailed reproduction steps.
