Error launching application: spawn EACCES.

When trying to launch my project through the UnityHub, It first asks me to download the correct unity. I decline and select 'open with preferred version'.

It then stops and gives me an error message that reads:
"Error launching application: spawn EACCES."

I haven't checked if it works fine with a correct unity version-project combo.

 

Hi! I had the same error. In my case Unity Editor has a "run as administrator" checkbox activated in exe properties window. Unchecking it helped me to resolve the issue. Good luck!

 

So how's its going?

Have same issue here.
