我下载了pyTranscriber-v1.4-linux-安装程序并按照以下脚本将其安装在 Ubuntu 18.04 上：
#!/bin/bash
mkdir -p /opt/pyTranscriber
cp -r app/* /opt/pyTranscriber
chmod +x /opt/pyTranscriber/*
cp shortcut/pytranscriber.desktop /usr/share/applications/
pyTransscriber 已成功安装并可以运行。但是，无论我在 GUI 中按下什么按钮，程序都会退出，无法执行任何操作。
是否存在我遗漏了的安装过程或依赖项，或者我做错了什么？
这是我运行时得到的错误输出/opt/pyTranscriber/pyTranscriber：
