Hello LGDMps,
Welcome to the Microsoft Community.
I understand that you are experiencing issues with certain PCs being unable to upload local changes, and you have tried many solutions without success.
Based on your description, the problem occurs during the process of uploading modified local files to the cloud. Such issues are typically caused by network-related factors.
You mentioned that you have tested the network but couldn't resolve the problem. I'm not sure what method you used to test the network. Please try testing with alternative networks (wired/Wi-Fi, home/personal networks) and also check the link below to attempt any methods you haven't tried yet.

Please also try the following methods to see if they resolve the issue:
1.To rule out interference from third-party programs, please perform a clean boot by following the link below. After the clean boot, do not open any other third-party programs and test directly to see if the issue persists.
How to perform a clean boot in Windows - Microsoft Support
Disclaimer:
A clean boot starts Windows with a minimal set of drivers and startup programs. This helps determine if background applications are interfering with your system and identifies the root cause of the issue. While the clean boot process may appear complex at first glance, carefully following each step in order will help resolve the problem efficiently.
2.To rule out any account configuration issues, I recommend creating a new local administrator account, then switching to it and signing in to OneDrive to test whether the same problem occurs.
- Click Start, type cmd, right-click Command Prompt, and select Run as administrator.
- In the Command Prompt, enter the following command and press Enter to create a new account:
net user aaa /add
(Replaceaaawith your desired username.)
- Then, enter the following command and press Enter to grant administrator privileges:
net localgroup administrators aaa /add
(Ensureaaamatches the username you set above.)
3.Please try accessing OneDrive web version directly in your browser and modify a file there to check if the changes sync properly.
