UPDATE!!! UPDATE!!! !!! UPDATE!!!

The solution I used worked, until I had to reboot the system. after rebooting the system the gpu was working however the display picture would rip and tear moving windows on it then return to normal etc. Also Nvidia would not open from system pref although it shows it. The Nvidia control panel would not show at the top bar where the time is. So with the tearing being a more annoyance then a problem bc the monitor and display would work, I had to find a real solution and thus I came across these instructions which I can confirm even after a reboot, SOLVES this issue.

Here’s the best current workaround, and brought my system back to life!. (by eierftucht on macrumors site)
Step 1. Physically disconnect the affected device from the web. Powering down the router for a few minutes will do just fine.
Step 2. Boot into
Safe Mode. Everything will be extremely laggy, be patient. (-x in clover will boot safe mode, safe mode is essential step..will not work otherwise)
Step 3. Launch Terminal and enter the command ‘sudo nano /etc/hosts’, once prompted provide the password. (You can also use something like little snitch to block trustd instead of changing hosts...in step 3 &4)
Step 4. Append the following lines to the file’s contents:
127.0.0.1 ocsp.apple.com
127.0.0.1 ocsp2.apple.com
127.0.0.1 ocsp.digicert.com
Save changes and exit.
Step 5. Run the following batch of Terminal commands:
crlrefresh rp
sudo rm -f /var/db/crls/*cache?.db
sudo date -u 020200002020
sudo reboot
Your computer will immediately reboot after the last command. Upon seeing the desktop again, you should notice that everything is back to normal. You can now reconnect to the internet. System time and date will automatically adjust themselves upon reconnecting. If some apps throw errors related to bad time and date, another reboot will fix that. Don’t worry if you run into any scary messages upon the first reboot.
The ‘sudo date’ shift trick is 90% likely unnecessary but better safe than sorry. It’s there just to lure the system (now reverted to a clean state) into repeating any sneaky moves it’s compelled to make since the 1st of June, just to check it no longer breaks itself.
good to go!

Alternative way is:
Restore from time machine from date before June 1st.
Completely disconnect from internet.
Boot restored system.
Open terminal.
Paste this, hit enter, type in pass.
sudo sh -c 'echo "0.0.0.0 ocsp.apple.com" >> /etc/hosts' && sudo sh -c 'echo "0.0.0.0 ocsp2.apple.com" >> /etc/hosts' && sudo killall -HUP mDNSResponder
Restart, reconnect to internet.
Good to go.
