Since i updated my Illustrator to the latest 2020 version, i get a list of about 15 or more plugins not loaded successfully...

i can open my project but then my work space is gone and all my drawing tools to the left are gone and i cannot do stroke, fill or shapes....my older version was working perfect... now my computer crashes every 15 min and i get errors of plugins not loaded when i start again....so frustrating i am about to cancel my membership.

i tried installing the older version i had and i still get the errors.
i haven't been able to finish my projects in the last 4 days!!!

Please help!
