SVG Thumbnail

Steps to reproduce

1. Open a folder that contains an SVG in File Explorer
2. Copy and Paste the SVG file
3. Create a shortcut (.lnk) to either of the files
4. Shortcut does not get a thumbnail, progress bar loads forever, timeout exception window eventually appears

Clicking continue resumes COM Surrogate's CPU usage, which does not cease even with cancelling the progress bar, refreshing or closing the File Explorer window, or force restarting Windows Explorer. If you kill COM Surrogate and restart Windows Explorer, then the thumbnail will generate just fine on re-opening the folder with no continued CPU usage.

While creating a shortcut is a reliable way of reproducing this issue, I am also getting this fairly frequently when simply saving a file from Inkscape into a folder open in File Explorer, which has been very frustrating.

✔️ Expected Behavior

Thumbnail is generated in at most a couple of seconds

❌ Actual Behavior

Thumbnail is not immediately generated, File Explorer progress bar appears, .NET Exception window opens somewhere with 0x800705B4, COM continues to use CPU indefinitely:

System.Runtime.InteropServices.COMException (0x800705B4): This operation returned because the timeout period expired. (0x800705B4)

Other Software

Nothing of note in the File Explorer logs, just initialising after each computer restart. Windows 10 21H2 (19044.1645).

Can reproduce this.
Ref MicrosoftEdge/WebView2Feedback#2054

EDIT: @jaimecbernardo adding priority 1 since explorer become unresponsive after hitting the error.

Can we implement the workaround mentioned in the WebView2 repo issue?
