Outlook calendar will not allow a date or time change to a scheduled event via the date/time pull downs

In my outlook calendar I can no longer change the date or time of any event using the pull down arrows to change the start date or time. When I input a new day or time, it reverts back to the original. I am able to change the date/time of event by dragging the event, but this is cumbersome. It is a new computer and Office 365. This is a new issue and started approximately 2 weeks ago.

    SORRY - IT ONLY WORKED ONCE then went back to the problem. So ignore the rest of this message. Just got it corrected. My PC, an HP Pavilion Desktop x64 just had a bios update. That corrected the issue. BIOS Mode UEFI . Running Windows 11 Home Ver. 10.0.26100 Build 26100

    I have the same Windows 11 version as you, however I use (and own) Outlook 2016 at this time. Never had an issue until this issue recently.
