Unable to download files from OneDrive, Explorer freezes

Agreed, very positive results! Update . . . tested the following each with OneDrive Sync Service disabled (confirmed with Task Manager). Start OneDrive manually -> finish syncing -> No manual shutdown of OneDrive: This results in the system shutting down, but then immediately restarting. This was tested 3+ times, allowing the system to reboot, wait 3 minutes, then attempt a shutdown. Start OneDrive manually -> finish syncing -> Manual shutdown of OneDrive: This results in the system shutting down, and a clean stop on the first try. Tested this 3+ times, allowing the system to reboot, wait 3 minutes, then attempt a shutdown. However, the system will always spontaneously restart on the 2nd or 3rd reboot. If I persist with additional shutdown(s), the system will shut down, but it takes a few tries, sometimes going back to a restart immediately after the shutdown. The shutdowns are relatively quick, and no forced shutdown is needed. Another glance at the processes running in Task Manager wasn't that informative. There is no obvious system 'hog' running. I can go through the list of installed programs and disable additional ones that aren't crucial and see what happens. In all, the tests above indicate DDPM was definitely involved. No other clear causes for the remaining hangup, that I can tell.

Thank you @Dale Sherman, PhD for the detailed testing.

At this point, the results show that Dell Display and Peripheral Manager was a major part of the problem, while OneDrive running during shutdown still triggers the remaining restart behavior.

To summarize what we have tried:

• Confirmed the files work normally on OneDrive Web and another computer.
• Confirmed File Explorer freezes only after OneDrive is started.
• Reset, unlinked, and reinstalled OneDrive.
• Completed the Windows 11 repair update.
• Ran DISM and SFC, with no system file corruption found.
• Checked both drives, which reported healthy.
• Checked wake timers and Event Viewer.
• Found a crash dump pointing toward the Intel graphics driver and Dell Display and Peripheral Manager.
• Uninstalled Dell Display and Peripheral Manager and Dell Core, which resolved the long shutdown hangs.
• Confirmed OneDrive still sometimes causes an immediate restart when it remains active during shutdown.

For now, I recommend:

• Keep Dell Display and Peripheral Manager and Dell Core uninstalled.
• Keep both OneDrive startup entries disabled.
• Start OneDrive manually when needed.
• Allow it to finish syncing, then quit OneDrive before shutting down.

This is currently the most stable configuration based on your testing. I would not disable additional programs at random.

Since OneDrive has already been reset and reinstalled, a permanent fix may require a future OneDrive, Intel graphics, or Dell software update. Please keep Windows and your graphics driver updated and continue using the workaround for now.

Thanks for your patience and for carefully testing each step.

If all is resolved, feel free to mark the answer for this thread. Otherwise, please let me know if there is anything else I can help you with.

Thanks!
