Corrupt save file

Guys my save file is obviously corrupt as cant fully sync it from cloud , gets to 98% then crashes at senna screen , I’ve reset xbox deleted local saves reinstalled the game about 7 times but just wont sync past 98% , I can load game and start from fresh but I’ve got over 500 cars and own every property & I’m halfway through 2nd prestige

Do you get as far as the sync failed message, with option to retry or cancel?

Anyone fixed this? I get to sync page on pc and i have waited over 4 days now and it’s stuck at Sync data 0%

started a new save game. all was lost.
