I had also this problem today. It was after the windows update.
The solution for me was:
Right-click the launch box file and select Properties.
Click on the Compatibility tab.
Under "Settings," click the Change high DPI settings button
Under "Program DPI," check the Use this setting to fix scaling problems for this program instead of the one in Settings option.
Using the available drop-down menu, specify whether an app should use the display DPI settings when you sign in to Windows 10 or when opening the app. -> Choose app
High DPI scaling override checked to Application
With this i was able to make the application font and text work as before.
