All my token storages changed to zero after the implementation

I have a ERC20 token deployed using the ERC196 Proxy using open-zeppelin contracts (Initializable, UUPSUpgradeable, OwnableUpgradeable, etc).

The problem is, the last implementation upgrade occurred 480 days ago (version 4.4.1). My team needed to update the code again and I imported the open-zeppelin contracts in remix.ethereum.
I think that open-zeppelin contracts received some updates (version 5.0.0) and some storages changed. Given this, we updated the implementation and all slots were reseted. The owner, totalsupply, proxyUuid, etc. Everything is with 0 value and I can't upgrade it again to the old implementation.

Is there something I can do?

Hey, you can find more about backwards compatibility in our documentation:

From what I read, sounds like the storage layout shifted and you’re probably not the owner of the contract or authorized to perform upgrades.

Please feel free to reopen but provide relevant addresses or code along with your question.
