major bug please help

I am using the same computer ive had for years and i used to be able to use a 2021.3 version fine and now i cant use any versions only a 2018 version works
anything newer i can download make a project but when i open the project it loads into my task bar but i cannot open it please help i thought it was system requirements but since the same computer cant use the same version of unity it used to i do not know what to do

Which means what exactly? I’m sure you don’t mean that you are unable to open the project. That would be a case for a physician, possibly. :wink: So what exactly is happening?

PS: check the editor.log for any errors. Feel free to attach it here.

The project is open but i cannot click on it to open it into full screen a hour or so ago one version from 2018 worked for about 5 minutes . I think it could have something to do with read and write permissions but i tried to change them and it did not work

PS i opened the licence audit logs and i saw this a few times
Licensed Package: False, Entitlement requested

i wrote a more detailed lissues i can see on the log files
HERE:

no matter what version of unity i install i cannot open a project it loads does the package manager screen loads into my task bar but i cannot open them at all i have checked the logs and found these issues

licencing client log :
Floating licensing service disabled: Invalid servicesConfiguration for licensing. Make sure the licensingServiceBaseUrl servicesConfiguration is a valid URL

licensing audits :
