The game freezes upon pressing the I (inventory) key

Hi, for a couple of days I have not been able to play anymore, because as soon as I press the I key, the screen does not show me the inventory, but a purple bar with TXT_TEXT and TXT_BTN written numerous times, the game crashes and sends me in crash report. I’m on the “Go to the Valklaken lookout point” mission. Even if I don’t press the I button, the game is now extremely slow in fps, and never has been (I have a GTX 1080). Any suggestions? I also tried to validate the system files with the Steam tool, obviously I’m talking about the PC platform.
