Provider extension builder shows weird form validation errors / TYPO3 9.5.1

[AlexanderKoe]

Filling out the Form at Provider extension builder causes weird form errors.
A correct E-Mail filled with my name-email combination is marked with "You shoud follow the pattern "Vendor.ExtensionKey".... at the same time the Extension Key input is correct too.
message seems to appear randomly, possible on next try id did not appear.
Changing in both fields do not have any affect, Message is not removed either.
Reload of form required. Another try with exakt same data works. Tried multiple times (> 10x)

does the Provider Extension builder work actually with typo 9.5.1? I mean did it work correctly after you succeeded?

Hi, I got it to work now with Typo3 9.5.1 and all GitHub versions of flux, vhs, fluidpages and builder. But in fact i got the same error as alexander: it demanded me to use Vendor.key for all four fields. So my Mailadress is now Goacademy.Provider :)
