In UE 5.4.4, the Pitch and Yaw scaling of the gun model in the third person character have been modified and enlarged. It cannot be recovered

In my UE5.4.4 project there are first and third person, when switching to first person, the model size is not changed, and the scale size shown in the details panel is 1, but when the third person model size is modified, the scale printed using PrintString is (1,1.119,1.119),. While the project is a multi-player co-op project, the problem only exists with my computer, and I have reinstalled the system on the computer and formatted the disk where the project is stored. When it is determined that the project has no problems on other computers, the project is pulled using SVN, but the problem persists.
