It will be challenging for me to debug the issue as it is not replicable from my side. Your best bet is to attempt some troubleshooting steps and, hopefully, identify the root cause.
Here are troubleshooting steps that you may check:
1. Before you download and install the software, please check that your machine System and Software Requirements are meet before installation. Ensure that your Operating System is supported.
2. Install currprocess https://www.nirsoft.net/utils/cprocess.html and disable all the software running behind.
3. Try restarting Quartus and your computer. This can help clear any temporary issues that may be causing the error.
4. Check your system resources, including memory, CPU usage, and disk space. Make sure you have enough available resources to run Quartus.
5. Try disabling any antivirus or firewall software temporarily, as they may be interfering with Quartus.
6. Try to re-download the Quartus .tar installation package and install again. Check that the installation files .tar is not corrupted by checking the checksum.
7. Make sure that your quartus directory folder are not in read only options.
8. Google for related issue on clipboard copy and paste. Here an example:
