"Unable to load frame's content" error when LN starts

User encounters the following error message on the workspace when starting Lotus Notes: “Unable to load frame’s content”. A pop up box will then show up with the following cryptic message: “2f:0f”. Clicking “OK” on the message box will then shut down the LN client.

This issue will happen regardless on whether I’m using the Basic or Standard client. It also persists after the Data folder (in %appdata%) was deleted.
