Don't start discussions about machine ressources, we've got several Altium licences on different powerful machines - they all have the same problems. And we're using Altium for years. It becomes worse from release to release. The update rate last month has revealed Altium's quality problems.
Cheap bugs, just that simple.
And: any software running only on Intel machines with such a high price is a bad software.
Well, then it's time to see the light like I did. Don't keep bashing your head against the wall
If your designs are not super complex, take a look at the latest release of DipTrace. It's great value & easy to learn, yet quite powerful.
If your designs are more complex, give a Proteus a try. A great UI & also pretty quick to learn.
Both will save you considerable $$ & there is no doubt you will live longer.
You can export your existing designs from AD so don't feel you're locked in.
There are plenty of alternatives out there & as I've said many times before, I do not like Altium the software & I more intensely dislike Altium the Company.
Take a deep breath & make a life changing decision that will reduce your future stress levels.
PS: With the money you save, take a well earned holiday .................... every year until you decide it's time to retire
