GetFileAttributes returns Error: (19, 'GetFileAttributes', 'The media is write protected.') for onedrive

Question

In below CPP code, I am calling GetFileAttributes  API to fetch file information. 

I have created VSS snapshot via <g class="gr_ gr_9 gr-alert gr_spell gr_inline_cards gr_run_anim ContextualSpelling" data-gr-id="9" id="9">wmic</g> <g class="gr_ gr_8 gr-alert gr_spell gr_inline_cards gr_run_anim ContextualSpelling ins-del multiReplace" data-gr-id="8" id="8">shadowcopy</g> call create Volume='C:\' and passing snapshot path to API.

It works fine when I am running it as process But fails when running it as windows service.

It fails only for one-drive folder and works fine for rest of file/folders on the system.

It failing after Windows10-1803 update.

#include <windows.h>
#include <stdio.h>
int main(){

    char *path = "\\\\?\\GLOBALROOT\\Device\\HarddiskVolumeShadowCopy195\\Users\\Win10\\OneDrive";
    FILE *fp;
    fp=fopen("C:\\trunk\\err_19_log.txt", "w");
    int res1 = 0;
    res1 = GetFileAttributes(path);
    fprintf (fp, "\\\\?\\GLOBALROOT\\Device\\HarddiskVolumeShadowCopy4\\Users\\Win10\\OneDrive%d\n",res1);
    fprintf (fp, "%d", GetLastError());
    printf("%d %d", res1,GetLastError());
    fclose(fp);
    return 0;
}
