Game lags after alt-tabbing

game becomes unplayable after tabbing out and back in. Abilities are rebound on screen to “BUTT”. I have no controller plugged in, no other input devices besides keyboard and mouse. Issue appears no matter the display mode, fullscreen. borderless window. I am on the most up to date NVIDIA graphics drivers. 3080ti, ryzen 75800x3d. I have verified files and steam found no issues. I also completely uninstalled and reinstalled last epoch completely.
