catalina – Accents menu is magically disabled without reason

Accents menu sometimes disappears without no reason, charter repetitions activates itself instead even if it isn’t disabled from the settings, and I have to reactivate it with:

defaults write -g ApplePressAndHoldEnabled -bool true

I had to set this command to be executed every time I open a new Terminal because it disables magically so often! It’s happening for months 🙁 Any ideas? Thanks in advance.
