locale error: unsurported local setting on Raspberry Pi 4

Hey everyone,
After using Intel Nucs for my Mill, I thought I try it on the small Raspberry Pi 4 for my Lathe.
But I encountered a Problems in the PnCConf Wizard.
Step bevor error:
Install the newest Linuxcnc Image for RP4 via Raspberry Pi Imager (No settings aplied)
Chance keyboard layout to german
sudo apt-get update
sudo apt-get install network-manager*
Change the ethernet IP Adress to 10.10.10.1
Start PnCConf Wizard
Select 7i76s
Do the first couple of pages until the page for the X-Motor comes up. (nothing special there)
Input a Value into the stepper Scale
Test the Stepper= it works.
Then the following error occurs.
 
I can´t read anything into the error message

Since than i tried:
My 7i76e: Same error
A Intel Nuc from my Mill: No Error, works just fine
Reinstall Linuxcnc: No change
Chance Raspberry Pi: No change
Searched the forum: Didn´t find my specific problem

And now I hope, you can help me with my error

 

I´m not sure, what to do.
I checked the locales and everything seems fine.
 
(don´t mind my tipo)

On the pi, please typeto set locale

Thank you for your help.
I brute forced it, by activating all locals. (After figuring out, that I have to use the "Spacebar" to activate the different settings xD)
It works, but I will try which one is the problem.
Next try I only activated only the de_ an en_ ones, which also worked
I´ll post the right one in this thread in the future.

The missing local was the:
en_US.UTF-8 UTF-8

I only needed this one activated. Now everything works.
