After I turned to 14.10.2-ce.0 from 14.9.2-ce.0 I can not create projects any more
In the browser I get a failure like:

The form contains the following error:

undefined method `encrypted_properties’ for #Integrations::EmailsOnPush:0x9cc853c8 Did you mean? encrypted_properties_tmp encrypted_properties_tmp? encrypted_properties_tmp= reencrypt_properties

from the command line I get :
git push --set-upstream ssh://git@example.com/user/$(git rev-parse --show-toplevel | xargs basename).git $(git rev-parse --abbrev-ref HEAD)

I remember when upgraded the rasperian, it also upgraded me the kernel.

right now it has this kernel

Linux gitpi 5.10.63-v7l+ #1496 SMP Wed Dec 1 15:58:56 GMT 2021 armv7l GNU/Linux

what happened?
