1) Transferred a save file with a single coach (Manager 1) from FM23 to FM 24, and played 2 months in game. No problems.
2) Added a new manager (Manager 2)
3) Advanced a week (during which I made two unique saves).
4) I quit and returned later in the afternoon to load my save. When I did so, I could no longer switch between the two managers. It was as if Manager 1 (maybe due to not having a profile in FM24) was not a user manager. He still existed at his same club, but there was no longer an option to switch to him on the top right. I would load directly into the Manager 2 profile with no option to switch. Retiring with Manager 2 would put me in the single-player observer screen, instead of switching to the other coach.

However, adding a 3rd Head Coach, AFTER loading the save would re-enable the UI list of player Head Coaches on the top right, where Manager 1, 2, and 3 would now show up. (selectcoach.png)
Switching back to Manager 1 would give me the pop-up asking to Please Confirm: Resume Control of 'Club' (pleaseconfirm.png)
CONCLUSION:
Adding a new Head Coach in the FM24 database that was transferred from FM23 breaks the UI of all future save files so that you cannot switch Head Coaches. Adding a new coach after loading the save fixes the UI as a temporary fix, but it has to be done upon each load.
