Language persistence error (Greek) in Windows 11 Home Single Language - Dell G3 3590

The system automatically switched to Greek and blocked all interface change options.
I am a user of the Single Language edition, and the base language pack seems corrupted.
I have tried to force the change through PowerShell and registry edits without success.
When attempting an 'In-place Upgrade' repair with a Portuguese/Spanish ISO, the system does not allow keeping applications because it does not recognize the current base language (Greek).


I am currently in the post-defense phase of my Ph.D. in Chemical Engineering. This technical bug is critical for me because it's affecting my access to specialized advanced modeling tools (Python) and process optimization data. I cannot afford a clean install as I must preserve my research environment and configurations.

    I can sense the frustration! As a Ph.D. candidate in Chemical Engineering, it's essential to have a reliable and functional computer system. Unfortunately, you're experiencing a critical issue with the language persistence error on your Dell G3 3590 running Windows 11 Home Single Language. The system has automatically switched to Greek, blocking all interface change options, and you suspect a corrupted base language pack.
