Call to undefined function

WP 5.4.2; PHP 7.2.31; MySql 5.7; LearnPress 3.2.7.2
After activating the plugin it shows me the following error and does not allow me to access the administrator panel, when I delete it manually everything returns to normal, the same happens if I try to activate Learnpress again:
