I can't change language in AoE IV Anniversary Edition

Hi, in AoE IV AE I can’t change the language to Polish. According to the instructions, I have the language set to Polish in the Windows 11 control panel, and the game starts in English all the time. Can something be done about it?

Afaik Polish is not supported.
For general instructions look here:

in Anniversary Edition is supported. I use this instruction. I can change to spanish, german and other, but when I try change to polish game back to english.

Try moving the language pack in windows to the top of the list of languages and rebooting, that is what worked for me.
