Hi, i hope you're doing good today.
This issue may happen when multiple language has been deleted accidentally or when it is missing.
As an initial troubleshooting step, I suggest you to check if multiple keyboard layout has been configured under Region and language settings.
Type region and language on the search bar.
Select Region and Language settings and check if you have installed multiple languages under a language pack.
This issue may also arise due to corruptions in Windows components and I suggest you to download and install any pending updates that needs to be installed on the computer through Windows update and check if it helps to resolve the issue.
Type settings on the search bar, choose Update and Security and click Check for Updates.
Regards.
