Nuendo 12 will not open while waves 11 is open

Nuendo 12 will not open while Waves 11 EL is open and visa versa, both programs worked fine in tandom before I updated from Nuendo 11 to Nuendo 12, both software I am running as administrator, I have uninstalled both programs and reinstalled, I have updated everything that I could possibly update and deleted older versions. I run windows 11 and have plenty of ram, I am getting a headache, help me if you can I’m feeling down.
