Hi @mikeliu and welcome to the forum!

The most recent version of OpenTAP is 9.19.4. I recommend updating to it.

Could you try listing your packages. You can do this by running “tap package list --installed” from your installation folder.

Thank you for your replay.
Actually, It is the problem of Win10 system.
By updating system, this issue is fixed.

Thank you again.
