Onedrive Issues and Syncing

i have been using Ondrive and it has been working well but now all of a sudden we cannot get material from the cloud to sync on the computer we are using. the Onedrive icon is still in the file explorer but the information is not coming back down from the cloud.

i have had a message saying there is an issue with onedrive and it should be reinstalled but everything i read online says that onedrive is built into windows 10 so it cant be reinstalled.

if anyone has a work around i would really appreciate it.

I haven't tried to do it cuz now I use a web app to sync files from OneDrive. But there's an instruction that may give a help for reinstallation in Windows 10 which I saw before:
1. Restart your PC before reinstalling. Once restarted, navigate to the following folder:
C:\Users\USERNAME\AppData\Local\Microsoft\OneDrive\Update\OneDriveSetup.exe
USERNAME is the username of the administrator account. You may need to enable Hidden Items in File Explorer to see this location.

2. The installer will begin to run and you'll be prompted to login to your Microsoft account. You may take part in two-factor authentication as well.

3. You'll be asked where to place the default OneDrive folder. If you didn't change this folder previously, it will be the same and you'll be asked to confirm its location.

4. Once installed, OneDrive will begin syncing anything you changed online with your offline files and vice versa.

I had a similar issue recently, and came across a product called WebDrive. It makes OneDrive appear as a drive letter on your desktop, and there is no need to reconnect and sync every time you need to access a file. I have been enjoying it so far.
