This appears to be very similar to a problem asked and answered on MS Answers.
The only two solutions are a) restore the most recent backup, and not from OneDrive which is only a current copy of the exact same accdb (that's how OneDrive works) and b) attempt the recovery method suggested in that other discussion, which is highly unlikely to work at this point.
It's not a question of being "willing" or "able" to help. You deleted a column from an Access table. The only way back from that is to restore a backup of the original table. As Jack and I noted in that other thread, there is the potential to recover a deleted table, but ONLY if the accdb in question has not been closed. I doubt that applies here.
As Arnel notes, you could create a new column using the AutoNumber IF that were the column actually deleted, but that will not restore any relationships created using it anyway. On the other hand, if Referential Integrity had been enforced on such a column, you would have had fair warning about deleting it, so my guess is that it was something else.
Good luck.
