I would lodge your complaint first with the attorney for the executor and make sure the attorney understands that the executor is a representative of the estate and owes a fiduciary obligation to all of the beneficiaries and if she cannot handle the responsibilities in an objective and fair manner then she should be removed or resign. If you attempt to remove her you will need to present evidence to the court that the court will objectively determine represents a breach of fiduciary duties, etc. You will need an attorney if you seek to remove her. Good luck.
