Works fine for me.

To resolve invalid dates in the Steam Screenshot Manager, try deleting or editing the corrupted screenshots.vdf file in your Steam folder, unblocking the screenshot files, and ensuring that the files themselves haven't been deleted from their directory, as this can cause the manager to display incorrect or missing information.

1. Locate and Edit screenshots.vdf
Find the folder:
Navigate to your Steam installation directory, then to userdata\ followed by your SteamID, and finally the 760 folder.
Open the file:
Open the screenshots.vdf file with a text editor.
Edit or delete entries:
Find and delete any entries related to the corrupted or invalid screenshots from this file.
Save and restart:
Save the file and then restart Steam to see if the issue is resolved.
2. Unblock Screenshot Files
Check file properties:
Go to the folder where your screenshots are stored.
Unblock:
Right-click on a screenshot file, select "Properties," and look for a "Blocked" message.
Unblock the file:
If the message is present, check the "Unblock" box to remove the block and then click "Apply".
3. Verify File Integrity
Check the folder:
Go to the Steam screenshots folder and make sure the files still exist in their correct locations.
Do not delete manually:
If you delete screenshots manually from the folder, the Steam Screenshot Manager will show a warning or error because the link between the manager and the actual file is broken.
4. Re-create the Shortcut (if applicable)
If the issue is related to a shortcut pointing to your screenshots, try deleting the shortcut and re-creating it to ensure it isn't corrupted.
By following these steps, you should be able to fix the corrupted date or file information in your Steam Screenshot Manage

I'm getting kinda wary of the first reply always being "works for me". That has a community management AI vibe to it.

Well, I'm glad you have no issues Jaunitta, good for you.
