DNI flow failed

[dster]

I am getting errors related to the DNI flow process when I compile my project. This is the error below:

Flow failed: Failed dni::save_checkpoint - The 'sandboxes/GC1-7CCVH84_3948_0/sld/sld_sysconfiles/FIFO.sopcinfo (text_model)' database could not be copied.

A database file, 'dni/sandboxes/GC1-7CCVH84_3948_0/sld/sld_sysconfiles/FIFO.sopcinfo', was not found on disk.

Another error I got was this one: 

Error: Flow failed: Failed dni::save_checkpoint - The 'checkpoints/<projectname>/user_runs/default_run/swept/sld/sld_sysconfiles/manifest.txt (manifest_text)' database cannot be accessed.
The 'checkpoints/<projectname>/user_runs/default_run/swept/sld/sld_sysconfiles/manifest.txt (text_model)' database cannot be accessed.
A database file, 'dni/checkpoints/<projectname>/user_runs/default_run/swept/sld/sld_sysconfiles/manifest.txt', was not found on disk.

I thought this was all auto-generated, so I don't know why it can't find the files it needs.

For reference, I am running quartus 25.1 pro on windows.

I have tried closing and re-opening the project, deleting the DNI folder entirely, and I keep getting this message or something similar (like the folder is in use by another process).

Have you tried the Clean Project command from the Project menu?

Also, since checkpoints are mentioned, maybe try disabling Fitter snapshots, though it's not clear why that would be causing an issue.  That's in the compilation settings in the Settings dialog box.

Do you get any errors with error number codes or do they all look like this?

I did try cleaning and it appears to have fixed my problem. Thanks

Awesome!
