Hello! Can you confirm the size of the spline hole? Could I also see a picture of the operator to which this handle attaches? Thank you!
A quick learner from East Lansing, MI says:
The inside hole on the handle is 3/8" diameter. And I've attached a photo of the other part of the window... Thanks :)

I'm not sure what to recommend. Your operator looks similar to our 39-027E, but this takes handles with an 11/32" spline like our 39-114 or 39-114L. You say your operator takes a 3/8" spline. You might be able to use either the 39-104 or the 39-286 handle, but these are meant for Andersen operators. I don't think you have that brand. I would triple check your measurements just in case.
