Okay after a few days of googling and trying different things I've finally found how to do this.好吧，经过几天的谷歌搜索和尝试不同的事情，我终于找到了如何做到这一点。
This happens because the app installer on Android 10 was updated and cannot access files on /storage/emulated/0 any more.发生这种情况是因为 Android 10 上的应用安装程序已更新，无法再访问 /storage/emulated/0 上的文件。
App installer accepts only content:links now.应用安装程序现在只接受内容：链接。
Apps like Total Commander and Dropbox use real directories like /storage/emulared/0 and pass "file:" links to the app installer.像 Total Commander 和 Dropbox 这样的应用程序使用像 /storage/emulared/0 这样的真实目录，并将“文件：”链接传递给应用程序安装程序。 That's why it doesn't work.这就是它不起作用的原因。
The solution was to install beta version of Total Commander now also sends "content:" urls.解决方案是安装测试版 Total Commander 现在也发送“内容：”网址。 It can be found here: https://play.google.com/apps/testing/com.ghisler.android.TotalCommander可以在这里找到： https : //play.google.com/apps/testing/com.ghisler.android.TotalCommander
