Error: Can't access JTAG chain

I can relate to your issue. I attempted to resolve it and it appears to be functioning properly now.

Below is my solution:

1. Follow the steps in the link. It works initially, but the problem resurfaces after a day.

2. It appears that the error message "Error: Can't access JTAG chain" was caused by a permission issue. In order to resolve the problem, I reinstalled Quartus (version 22) as the root user, and this successfully solved the issue.

3. It's a good idea for a regular user to launch the program, as it avoids the need to constantly switch users. To grant others the same permissions as the root user, I utilized the command `ruibin@E590:/media/ruibin/Data/01/2531/quartus/quartus/bin$ sudo chmod u+s *`.

4.If you come across this issue: Quartus displays an error message stating "error while loading shared libraries: libprotobuf.so.14: cannot open shared object file: No such file or directory." see: https://www.intel.com/content/www/us/en/support/programmable/articles/000093063.html

I understand that launching the software as a root user may not be the best approach, but it seems like the most direct solution to my problem. If you have any other suggestions, please share them with me. Thank you!

Also, I hope my response can be helpful to anyone else who is facing a similar issue.
