Check network connection:
Ensure that both PCs are connected to a stable network and check if there are any network restrictions (such as firewall settings) that may affect OneDrive synchronization.
Manually trigger a sync:
In the OneDrive client, try manually triggering the sync operation to see if it resolves the issue.
Check the synchronization status:
Check the sync status in the OneDrive client to confirm if there are any errors or warning messages.
Resolve synchronization conflicts:

Clear local cache:
Try clearing OneDrive's local cache, then logging back in and synchronizing files.
Update OneDrive client and operating system:
Make sure the OneDrive client and operating system are up to date to get the latest features and fixes.
