Agreed. I had the same problem with that error. My backup was incomplete too, so I manually copied my important files to an external drive before trying the upgrade again.

Can confirm. Yeah, that error's a pain—did you check if your PC actually meets all the Windows 11 requirements, like TPM 2.0? Hope that helps.

Yeah, and just to add, double-check your antivirus software is fully updated or temporarily disabled, as that can sometimes trip up the installer too.

I had the same problem. The backup tool missed a ton of my stuff, so I ended up manually copying my important folders to an external drive before the upgrade finally worked.

Same here. You could also try creating a full system image backup with a tool like Macrium Reflect before attempting the upgrade again.
