Cannot change keyboard layout or use emoji keyboard on iPhone Mirroring after updating to iOS 18.5 and macOS Sequoia 15.5

After updating my iPhone to iOS 18.5 and my MacBook to macOS Sequoia 15.5, I can no longer change the keyboard layout by clicking the globe/fn key on my Mac, or open the emoji keyboard using the shortcut Control+Command+Space on my Mac. None of the keyboard shortcuts are responsive now, after pressing the keys, there's just nothing happens on my iPhone and my Mac. It just worked properly in previous versions and this evening after I update the iOS and macOS, it doesn't work at all! I tried to reboot both my iPhone and my Mac but it fixed nothing, the issue just persisted. This is a very big issue since I often and almost only use iPhone Mirroring to type text to my iPhone (especially on the Journal app which is still not available on macOS), if I cannot change the keyboard layout, then this feature just becomes useless at all! So does anyone encounter similar issues to me? Or is it just my own problem? If so, are there any solutions or workarounds to this issue? It is very annoying and I hope it can be solved ASAP!
