Adobe Acrobat is preventing Windows from automatically turning off the display and entering sleep.

The issue occurs simply by opening Acrobat and leaving it on the Home screen. No PDF or other document needs to be open.

Windows power settings are configured to turn off the display after 3 minutes on battery.

When Acrobat is completely closed, running:

powercfg /requests

returns:

DISPLAY:
None.

The display then turns off normally after the configured 3 minutes.

When Adobe Acrobat is opened, with no PDF or other document open, running:

powercfg /requests

returns:

DISPLAY:
[PROCESS] \Device\HarddiskVolume3\Program Files (x86)\Microsoft\EdgeWebView\Application\152.0.4191.66\msedgewebview2.exe
Video Wake Lock

The display will then remain on instead of turning off after the configured timeout.

Closing Acrobat immediately removes the Video Wake Lock and Windows display timeout works normally again.

I have confirmed that the WebView2 process generating the issue belongs specifically to Acrobat. Its command line includes:

--webview-exe-name=Acrobat.exe
--webview-exe-version=26.2.21901.0
--user-data-dir="C:\Users[username]\AppData\Local\Adobe\Acrobat\AVWebview2\DC\EBWebView"
--autoplay-policy=no-user-gesture-required

Troubleshooting already completed:

1. Confirmed Windows power settings are correct.
2. Confirmed display timeout works correctly when Acrobat is closed.
3. Confirmed issue occurs with Acrobat open and no PDF open.
4. Repaired Adobe Acrobat installation.
5. Updated Adobe Acrobat.
6. Restarted Windows.
7. Confirmed Acrobat multimedia/3D playback is disabled.
8. Disabled Acrobat launch messages.
9. Tested Acrobat online/cloud-related preferences.
10. Completely reset the Acrobat WebView2 user data folder by renaming: AVWebview2\DC\EBWebView and allowing Acrobat to create a new, clean EBWebView profile.

The Video Wake Lock is recreated immediately even with the completely new WebView2 profile.

Expected result:
When Acrobat is idle and no document or multimedia is being played, Acrobat should not generate a Video Wake Lock. Windows should turn off the display and enter sleep according to the configured Windows power settings.

Actual result:
Simply opening Acrobat causes its Microsoft Edge WebView2 process to generate a Video Wake Lock which prevents the display from turning off automatically.

Closing Acrobat removes the power request immediately.
