Help needed, comment on Instagram posts only one letter,

I have a simple script, that is supposed to post a comment on Instagram, but it only posts the first letter of the text (“Testing comment script!”).
I use UI.vision Version 9.3.8, and Brave browser
Version 1.73.97 Chromium: 131.0.6778.108 (Official Build) unknown (64-bit)
running on Linux Mint 22 Cinnamon ver. 6.2.9.

can anyone help me out with what is wrong?
thanks
