#'
#' @title Check Error Details
#' @description A function to analyze and provide guidance on how to fix an error message copied from the R console.
#' @param Summary_nch An integer specifying the maximum number of characters for the summary.
#' @param Model A string specifying the model to be used, default is "gpt-4-0314".
#'    Currently, "gpt-4", "gpt-4-0314" and "gpt-4-0613" can be selected as gpt-4 models.
#'    Execution with GPT-4 is recommended.
#' @param language A string specifying the output language, default is "English".
#' @param verbose A logical value to control the verbosity of the output, default is TRUE.
#' @param SlowTone A logical value to control the printing speed of the output, default is FALSE.
#' @importFrom clipr read_clip
#' @importFrom stats runif
#' @return The function prints the guidance on how to fix the error message.
