Hi @ScottHu,

Thank you for posting in Intel community forum and hope this message find you well.
Currently we are experiencing some issues with WSL 1 upon window updates.
However available patch has been release to solve this, please refer to the KDB and installed the relevant patch according to your Quartus version.

Warm regards.
