@scarfoxnyeh Just gave it a go but unfortunately it didn't work. Thanks anyway!

@jocelynleung just some additional info

Platform - PS5

Steps
1. I removed the game via the PS5 menu
2. I reinstalled the game via disk
3. I downloaded the 1.02 patch via automatically via the PS5 network
4. I opened the game via the PS5 console screen
5. I went to load game and the following message occured (Game needs to install - 00% etc.)

Other notes:
- Some save filed have corrupted
- I have attempted to proceed both online and offline, neither have helped

I have had to reinstall AC Valhalla due to patch 1.02 disappearing and refusing to download on my PS5.

I now cannot continue with any of my saves. It keeps showing install in progress, 00% complete. What can I do? I really don't want to start from scratch.
