Hello,
Can you right click on the cloud and quit, then relaunch OneDrive to see if you can access settings?
If not, try to uninstall via Settings > Apps > Installed apps, then restart, and install again. You can download it from here: https://www.microsoft.com/microsoft-365/onedrive/download
Once you have the OneDrive app up and running again, please follow these steps closely:
- Right click on the OneDrive cloud icon on the lower right on your taskbar to go to Settings.
- On the "Sync and Backup" tab, click on "Advanced Settings" to expand that section. Then under File On-Demand, click on "Download all files".
- Give it plenty of time to allow the files to be downloaded from the online cloud. On your computer's file explorer, you can observe the OneDrive folder and its folders/files inside. You want all of the green checkmark icon to turn solid green with a white checkmark. Depends on how many files you have, this process can take a while, so please be patient.
- Once all of the folders and files turn into the solid green icon with white checkmark, you can go back to OneDrive Settings. Very important - click on "Manage Backup" button, then turn off all folders listed there.
- After you turn off the folders sync in Step 4, now go to Account tab, click on "Unlink this PC"
- Go to your Windows Settings > Apps, find OneDrive and uninstall it.
