internal error: !xdata.cpp@1809 - Please help!

Hi all, 

 

Working in Civil3d 2024 and have had this error pop up in one of my modelling drawings (has a few data shortcuts, surfaces, featurelines, gradings etc). I tried all the old methods (-recover, getting old Superseded versions, restoring previous versions from onedrive, copying to different locations on the server, changing file names) and nothing has worked to be able to recover the drawing and get past the error. Co workers are also getting the same error in the drawing. 

 

I since re-created the old drawing from scratch which is working fine now but the error has moved onto a different drawing that was working fine two days ago. 

 

Does anyone know how to fix this error or what could possible be causing this so I can prevent it infecting anymore of my drawings? Otherwise I'm going to be chasing my tail re-creating drawings until they continue to break which isn't feasible at all for the project I'm on. 

 

Currently trying a total uninstall and reinstall of C3d but don't have high hopes given other co workers are getting the same error when trying to open the drawing. 

 

Error report attached as well hoping someone might be able to give some advice or guidance.

 

Thanks so much in advance for any help!
