Update: Game sort of runs now
Hello @EA_Illium, as of today I wanted to provide you with an update in hopes this information is helpful to you.
This morning I tried playing wild hearts and was continuing to get the same loading crash issue as mentioned before. I decided to play a different game instead with no issues for it crashing on my PS5 (the game is also digital). I ended up have to take care of a few things and left my PS5 running with the other game I was playing on idle for about 40 minutes. I came back and decided to try one last time to launch and play Wild Hearts and for whatever reason, I was able to get through the loading screens and get into the game without it crashing for at least an hour or two.
The game did still crash here and there; notably at times for a cut scene (mainly when encountering a monster for the first time), if I fast traveled to another camp on the same map, or if i was idle for more than a few minutes. However, after the crashes I was able to load up the game and continue to play without any issues until the next crash another hour or two apart.
I wanted to give you an update in the hopes that this new information could possibly help as well. I can't say for certain at this time that it is or will be a consistent work around as I haven't turned off my PS5 since that point I got the game to work. I will provide a second update to this one if there are any issues with the game trying to launch it tomorrow or if this current work around works again.
