Hello GardenofEden91, thank you for posting and sorry to see this is affecting you after the latest update.
This issue is caused by a corrupted local save and can often be resolved by replacing it with a new save file.
To resolve this issue we recommend following the steps in the article Ubi-Koality gave above -

Deleting this file will reset the settings, loadouts and Situation progress, so you will have to set up settings and customisation options.
You will not lose your level, renown, R6 credits, operators or season pass, but you will have to make sure you log in with the same Ubi Club account.
Can I confirm if both of you are PS4 users?
