Hello @jst-odog, thanks for getting in touch with us about your credits >
If you have tried multiple times in a short space of time to make a purchase, or you have had multiple payments fail to go through, your account may have been blocked from making any further credit purchases by Steam and Ubisoft for security reasons. In this case, please wait a full 24 hours before trying to make any further purchases.
If this is not the case for you, would you please try the following fixes to help resolve these credits issue, as they have helped players with the same issue in the past >
FIX 1: If using a VPN, please disable this before making a purchase.
FIX 2: Make sure your Steam overlay is enabled and try disabling your Ubisoft overlay >

FIX 3: We have found that for some players, purchases can be affected by what Steam Store Country you have listed on your Steam account and what currency you are using to make the purchase. This currency needs to match the country you have listed on your Steam account.

FIX 5: If you have both the Vulkan and DirectX versions of the game installed, please try making a purchase on both versions of the game, as some players have had success on one version of the game, whilst being unable to purchase on the other.
Fix 6: Delete any temporary download cache files in your Steam game launcher, that may be using up resources and memory and causing conflict >

FIX 7: Alternatively, instead of using the in-game store, please try purchasing credits with your linked Ubisoft Account, via our Ubisoft Store. These credits will be available in all PC versions of the game >
