Base on my experience on supporting this type of issue, can you help to check in the below?
1) install currprocess https://www.nirsoft.net/utils/cprocess.html and disable all the software running behind there
2) disable the anti virus
3) close all the Quartus software
go to c:/user/<username>/ rename the quartus2.ini and quartus2.req for windows
cd to home/<user>/.altera.quartus rename the quartus2.ini and quartus2.req for linux
and reopen the quartus. this will reset the initial setting of the quartus prime.
4) did you install all the devices?
5) check if you have spaces in your directory names? If you had, try to replace the spaces with underscores.
6) delete .altera.quartus
7) Make sure all your folder are not in read only options.
Let me know how it goes after doing all the debug steps,
