DataGridViewTextBoxCell has a static DataGridViewTextBoxEditingControl which is disposed by a call to DetachEditingControl. This causes a crash in the next call to InitializeEditingControl. The simplest fix is to check for editingControl.IsDisposed in that method, and creating a new one as needed.
I'll submit a pull request with the proposed fix shortly.
This has been fixed in the current sources (ie, since 3.4).
