As most of you know Adobe has formally stopped all support for Adobe Flash games as of Jan 12th 2021 and Google Chrome also stopped supporting it as of Dec 31st 2020
So here is a really easy solution!
download the 32 bit version of Pale Moon browser https://www.palemoon.org/download.shtml and install it
Make sure all previous versions of Flash have been uninstalled from your computer.
Then download the last version of flash before the Adobe Kill switch was added ie V18.104.22.1681 http://andkon.com/arcade/install_flash_player.exe and install it
Go to your favourite flash game in the Pale Moon browser ie http://game.poqery.com and it plays!

ALTERNATIVE 2 - get it working on Firefox
You can also view https://community.adobe.com/t5/flash-player/flash-player-stops-working-after-12-jan-2021/m-p/11759658?page=1#M210950 where they get it working in the Mozilla Firefox browser, although it appears to be a little more complex involving editing permissions and files. This solution is:
1) Install firefox 78.6.1 esr from this link https://ftp.mozilla.org/pub/firefox/releases/78.6.1esr/win64/en-US/
2) Edit the mms.cfg file C:\Windows\SysWOW64\Macromed\Flash\mms.cfg
