Hi @Athryn,
Apologies for the late reply. Have you managed to resolve this issue?
If not, I suggest walking through the steps of this Blank / White / Pink Screen Bug – particularly deleting the “Supernotes” folder located in Windows: C:\Users\<you>\AppData\Local\, as this is often not removed by uninstalling the app. It may have a slightly different path but it will be there!
Deleting the app, removing this folder and re-installing the app should definitely fix your issue. Please let us know if not.
