Weird bug in Excel 2024 LTSC when switching sheet direction (RTL issue)

Hey everyone, I ran into a strange bug in Excel 2024 Professional Plus LTSC (running Windows 11 25H2).
Whenever I open a new workbook and change the sheet direction from Left-to-Right to Right-to-Left, I can’t properly select cells anymore.

Clicking on any cell, row, or column doesn’t show the selection border — it’s like Excel doesn’t highlight anything. I have to click multiple times to make it respond.

This only happens after changing the direction. If I keep it Left-to-Right, everything works fine.
I tried reinstalling and even tested Excel 2021, and the issue doesn’t exist there.

Seems like a bug specific to the 2024 LTSC version. Has anyone else seen this or found a workaround?
