Revit 2026 Sync problem

Hi, I am having an issue with Revit LiveSync. Every time I open my project, walls and parts of the model have shifted to random locations, assigned textures are gone, and the whole model appears corrupted. I have to recover a backup file and save it again. After several syncs, the problem happens again. At this point the software is becoming unusable. I am using Revit 2026 and the newest version of D5. We are using shared coordinates. We did not have this problem with the earlier version of the software.
