save_image Error

Dear All,
I am using R 4.6, and i run the following code

 reticulate::use_python(reticulate::install_python())
 reticulate::py_require(c("kaleido", "plotly"))
  p <- plot_ly(x = 1:10)
  tmp <- tempfile(fileext = ".png")
  save_image(p, tmp)

I get the following error

Error in py_run_string_impl(code, local, convert) : 
    File "<string>", line 1
    import json; fig = json.load(open('C:\Users\310677\AppData\Local\Temp\Rtmpq0iC7T\filec73864b9a23.json'))
                                      ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape
Run `reticulate::py_last_error()` for details.

then i run r reticulate::py_last_error()

Please advise.

从 plotly::save_image(p, tmp) 开始，跟踪 kaleido()$transform 到 reticulate::py_run_string(load_json)；使用所示的临时路径在 Windows 上复现该失败。完成标准是 JSON 成功加载，并且 save_image 写入 PNG 时不会出现 Python unicodeescape 错误。
