A sub-assembly file in SOLIDWORKS was corrupted when it was being saved to 3DExperience. When I try to open it, it displays "Preparing data" (Image 1 attached) and then gives the error "An attempt was made to access a file that is exclusively opened by another application" (Image 2 attached). This file is not open in any other application and cannot be opened by anyone in my 3DExperience team. Furthermore, this sub-assembly is part of a larger parent assembly that also gives the same errors when I try to open it. I have tried multiple solutions including: restarting/reload from server, trying to overwrite the corrupt file, decoupling the child sub-assembly file from the parent assembly, and creating a new parent assembly. None of these solutions have worked and many other possible solution cannot be done because neither file can be opened. Deleting the parent assembly is a last resort since there a hundreds of references in that file that would take tens of hours to remake. If anyone has any ideas how to remove the child sub-assembly from the parent assembly or overwrite the child, it would be very appreciated.
