There have been many changes to both snarkOS and snarkVM recently, could you pull the latest commits and try again?

Thank you,
I did git pull. But same result.
I think you should check error message then fix issue.

I haven't been able to reproduce so far, as a sanity check, you are on commit cf9f4a488802655235b06f0d7d38903c7af5bd5e?

[hryksbt]

I got the reason.
run-client.sh cannot work with sudo command.
I need to be a root user. Then it works.
If this is unexpected, please consider to update.

Thank you,

Glad you got it working. run-client.sh works fine for me with sudo. Closing this issue as it seems to be resolved.
