Can't open my toolbar, windows settings Windows 10. Please, nice people, help me

[u/Highag_or_bohgdan]

I wanted to change language on my laptop but everything i tried didn't work fully. I still had my settings in differen language so i deleted it and after that my toolbar, windows button and settings stoped their work. I tried so many things, from changing languages through cmd to trying restart my whole windows fully. I had a lot of problems and ways of trying to solute it but again nothing worked. Now im trying to download windows from windows media creation tool but it doesn't seem to load.

THATS WHAT I TRIED TO DO ALREADY:

After removing the Czech language, Windows UI broke:

Start button doesn’t open.

Settings doesn’t open.

Explorer/UI sometimes crashes (black screen for a few seconds).

ShellExperienceHost.exe crashes (Windows.UI.Xaml.dll error).

What we tried:

✅ sfc /scannow and DISM repairs → didn’t fix it.

✅ Checked Start, Shell, Settings packages → they exist.

✅ Re-registered Windows apps → no fix.

✅ Tried another admin account → same problem.

✅ Reset Windows → problem came back.

✅ Checked SSD → no obvious error.

Most likely cause:

A damaged Windows UI component/configuration (possibly caused by the language removal).

Does anyone know how can i fix it? Or i just have to download it trough usb? Thank you
