我已经安装了 protonvpn，并且已经使用很长时间了，没有任何问题。
我已经使用过本教程 -https://www.tecmint.com/install-protonvpn-in-linux/ 安装protonvpn
从今天开始，尝试连接 protonvpn 时突然出现以下错误 -
sudo protonvpn connect
Traceback (most recent call last):

dialog.DialogError: dialog-like terminated due to an error: the dialog-like program exited with status 3 (which was passed to it as the DIALOG_ERROR environment variable). Sometimes, the reason is simply that dialog was given a height or width parameter that is too big for the terminal in use. Its output, with leading and trailing whitespace stripped, was:
Error: Expected at least 5 tokens for --menu, have 4.
那么，我该如何纠正这个问题？
