Hi Anthony,
Thank you for your fast response.
When the issue began I got in contact with support from the platform that hosts and develops the game and they gave me this link
https://support.ubisoft.com/en-GB/faqs/000026541/Game-crashes-with-Microsoft-Space-Storage-Device/
I got in touch with customer support but nobody was able to help me change the mode part from Microsoft Space Storage Device to something similar to what my C drive is above.
Many thanks and stay safe
