Describe the bug
After installing mantidworkbench from Conda, it does not launch, with the following error:
qt.qpa.plugin: Could not find the Qt platform plugin "windows" in ""
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
To Reproduce
Create a new Conda environment and install the nightly mantidworkbench package:
conda install -c mantid/label/nightly mantid
Attempt to launch with the command workbench
Expected behavior
Workbench should launch.
Screenshots
Platform/Version (please complete the following information):
OS: Windows 10
Mantid Version: Nightly since Qt moved to 5.15
Additional context
This has been hapening since qt was upgraded to 5.15. There is a workaround, which is to set the plugin path env variable:
conda env config vars set QT_PLUGIN_PATH="<path_to_your_conda_environment>\Library\plugins"
