Lasertank won't start

Lasertank hasn't been working since the Windows update KB85086672.
I've tried everything, but my favorite program still won't start.
Is anyone else having the same problem?
Please help me!

I have Win 11 Home 25H2 and my LT works as expected but I don't have KB85086672 installed. It's an optional update. Try uninstalling it.

I had the same problem with this update last week. After uninstalling it, LT worked perfectly.
How can I make sure I don't get offered this (optional) update again?

Have a look here. You'll need to download a program from Microsoft.

Thanks for the link. I downloaded and ran the tool.
A message with a yellow background appears on the page:
Troubleshooting has been postponed, and this tool is no longer being developed.
When I click “Next,” I select “Hide updates,” but the list doesn’t include KB85086672—only a security update for Microsoft Defender.
So I canceled the tool.
The link above also includes another method using PowerShell, but it doesn’t work for me. My version of PowerShell doesn’t have the Get-WUList and Hide-WindowsUpdate -Title commands, even though I’ve updated PowerShell to the latest version.
Tough luck.
