Unable to Access O1 Pro Mode – Assistance Needed

For the past two days, I have selected the O1 Pro Mode as usual, but the interface that appears does not reflect the Pro Mode settings. It seems that I have lost access to this mode entirely, which has left me quite confused and distressed.

I would like to know why this is happening and how I can restore the O1 Pro Mode to its proper functionality. The inability to use this mode is causing me significant inconvenience.

I hope someone can assist me in resolving this issue. Thank you for your help.
