When I click the document sharing button, the file open window does not appear or there is no response at all.
The file opening system may not work normally due to problems in your PC environment.
As a test, if the file browser does not open on the site below, the browser function of your PC is not working properly.
Please follow the steps below.
1) Reinstall chrome
2) Update your OS and reinstall if needed (PC reinstallation)
