I suggest adding checks for background and textView here.

I am on android 10, and have same problem. in the logcat it shows, process is bad.

I found a temporary solution, according to this, it could be fix by starting an activity of app (termux-api here). But as termux-api is not launchable app, you cannot run it from launcher instead you can run it with command "am start -n com.termux.api/.DialogActivity" in termux. and termux-api will start working.
