I am facing such issue

Error while initializing license client: Could not acquire lock file for client. Some other process might be using it.
Error! Cannot acquire license to use qtframework.

If you have a valid commercial license, please create a bug report to Qt Bugtracker:
https://bugreports.qt.io/projects/QLS

Attach the above error details to the bug report.

Additionally, attach the qtlicd_log.txt file of the Qt License Service that can be found from the directory of this Qt installation.
