WhatsApp Native App on MacOS stopps accepting new input characters

MacOS 15 latest. MacBook Pro M2.ARM
WhatsApp Native App (not web.whatsapp.com) - latest
LanguageTool Desktop 2.2.16 (latest)

After a couple of inputs (unknown what is the actual cause) in the WhatsApp, sometime the input field in WhatsApp doesn’t accept new Characters from the keyboard. Like, the input field is not selected.
After shutting down and starting up, it works again.

Now I also had the Problem with Windows 11 and the WhatsApp for Windwos.
