You have more than one storage device with a fc 26 profile

Same here 

The only solution so far would be to delete your save file. The old method of fixing it doesn't work for me. The one involving the auto sync

This is outrageous, you have caused me mental pain and suffering, three careers wasted, why did I pay for early access to the game if there is such a bug that I cannot save my career progress, terrible. I'm not some drooling kid, but a 37-year-old man who is literally having a nervous breakdown because of you. You will answer for this if I have the will and desire before the court. It's easiest to take the loot, and the players experience stress because of your irresponsibility.I will be posting problem like this on every possible gaming site, this is a shame. Thank you for another great version of the football game. BRAVO

I was loading onto EA FC 26 on Xbox SX fine earlier that day, but now I load onto it again, I'm receiving an error saying "You have more than one storage device with a FC 26 profile. Please select a storage device to load from" I have restarted my Xbox, deleted the game and reinstalled it, nothing had fixed it. Seriously EA? A week in and my game has stopped working completely to the point where I can't even load the game anymore

When I start the game EA FC 26, the error message “you have more than one storage…” appears immediately. I can't skip this message. I restarted the game and PS5 but nothing helped. I don't know if the game update could have caused it, because nothing like this happened to me before. So for two days I can't start the game at all and I can't play it at all.

You have to delete your saved files to be able to play the game same issue as in fc25. We are waiting for them to solve it. In fc25 it took 2-3 months to solve that. We are all disappointed to see that bug again.

Huge problem, I don't know if it's randomly throwing an error or generally for all people, I mean paying full price to enjoy career mode from the start without being able to save your progress for every player who doesn't play ultimate mode is a tragedy. The problem is that fixing that bug can take a while and we are not offered anything as a solution to the problem, if nothing else at least a refund of the costs.

Yes but that way you lose your career progress and that mode is completely out of order, I've restarted 4 times and every time I get the same error and that's it. Disaster

This happened in eafc 25 also, it happens if you use ‘Checkpoints’ save method, and ‘Main slot’ for same career.

I have the same problem on my ps5. Apparently it's the same bug from last year, it took them 2 months to fix it. I mean, terrible, I started 4 careers and every time the PS shuts down it gives me that error and that's it, you have to delete the saves from the disk and start again but it's better not to start the career because you'll have a nervous breakdown
