    I've been looking into this issue and it very much seems to be a UI related bug.

    The OpenXR loader has a custom loader ui, and in the DrawElementCallback method of the XRLoaderUI class and if statement is present which checks for this.
    If this is true, the 'toggled' property of the LoaderInformation is set to the value of the 'IsLoaderEnabled' property of the customLoaderUI. I don't know why this happens, but for OpenXR this property results to false.
    All of this causes the ui toggle to toggle off and remove the OpenXR loader again from the XR settings one frame later. (Not visible in editor but if you log the active loader you can see it).

    WORKAROUND:
    Close the XR settings window before applying your changes from code.

    Tested on:
    Unity 2021.2.13 & 2021.3.16
    XRPM: 4.2.0, 4.2.1, 4.4.0
    OpenXr Plugin: 1.5.3 up to 1.9.0
