AutoCAD 2030 .dwg File Assistance

I need help with a .dwg file saved via AutoCAD 2020. I'm having trouble opening it using my AutoCAD 2030 due to an error message stating "the file was saved by an application not developed or licensed by Autodesk". I require an expert skilled in resolving such compatibility issues or someone who can provide a viable workaround. Ideal candidate should have:

- Proficiency in AutoCAD, specifically versions 2020
- Excellent problem-solving skills
- Experience with file compatibility issues between different AutoCAD versions
