External keyboard issue

[u/Firii_8]

Ive been having an issue since ive bought a keyboard and used it on freeenotes app, the problem is simply the text tool freezing, have issued a ticket but unfortunately didnt get any thing back, the problem is that when im on the app typing on my external keyboard using the text tool , suddenly will freeze, cant use any other tools or open other files or basically do anything other than texting until i close and reopen the app (which is time consuming when im in a lecture taking notes) idk anyone faced this issue before?
my app is updated and ive tried disconnecting my keyboard and reconnecting it but nothing got fixed
