Hi @Aldemir ,
I’m not quite sure from this if you are trying to open the knime workflow from the One Drive copy, or from the workspace on your PC.
If from the One Drive copy:
From your screenshot it looks like some of your workflow subfolders are only “on the cloud” (those one with the cloud icon). These aren’t physically occupying space on your disk. The ones with the green tick are present locally. For KNIME to be able to use the subfolders containing details of the nodes, I would expect that the files have to be locally present, as KNIME simply trying to access references to them is probably not enough to cause One Drive to download them for you.
This is probably why the details for those nodes appears to be missing.
Try right-clicking on all those with the blue cloud icon, in Windows Explorer, and choosing “always keep on this device”.
Further info re One Drive icon meanings:

If from a physical workspace on your PC
Looking at the log and the screenshots, the log is trying to find the files in:
c:\Users\EFIM\knime-workspace but this is not the location in OneDrive, so I want to check if you have actually physically copied the backups from onedrive into the expected workspace location?
(maybe post a screenshot of the workflow folder and its subfolders, to check everything is there)
