Same issue, I played this morning even - no problem (except of menus in franchise loading longer)

same for me :(

Same for me, I wonder, an update of the game and impossible to start the game, the problem must be general
(test another game which starts perfectly)

Try adding -watchdog 0 to the start options in steam.

First step is to verify game files through steam. Next is to confirm all system files and windows are fully up to date. After that confirm that your antivirus is not blocking any part of Planet Zoo.
That's the basics. There does seem to be an issue with the game connecting to it's servers causing this. We are waiting for a patch. It seems likely to be server side and might be corrected on the weekly server update on Tuesdays.

Same issue here after installing the update today.
Game files have been verified. The game starts to load then abruptly stops.

Same here

I had the same issue earlier today, right after the update. The game wouldn't launch. I looked for some solutions on the internet. What worked for me was to right click the Planet Zoo exe file, choose properties and there set the compatibility to Windows 8. Works no problem since then. Hopefully it works for some of you as well.

Some players might need to check if microsoft redistributables need repair or update. They are found in windows/settings/apps. Some that have geforce experience installed will need to update that to the latest version.

Thank you! This worked for me too. I hope they issue a fix soon, as it should run on Windows 11 (as it was doing without an issue prior to installing 1.17.1 today).

So, I put in a support ticket for this issue and they sent me lots of information on how to resolve it.
However, before I started on everything that they had suggested, I turned off the compatibility mode that I had applied for Windows 8 which had given me a temporary fix.
I then attempted to launch the game, and lo and behold......it started up!! YAY!

Anyone have any idea why this would work?
