Do not use Termux app from Google Play. It is deprecated.
Use Termux application from F-Droid, here is the link: https://f-droid.org/en/packages/com.termux/. Google Play variant is deprecated, doesn't receive updates and contains issues as well as outdated repository URLs.

Before migrating to F-Droid Termux version, uninstall the application and all add-ons like Termux:API, Termux:Styling, Termux:Widget and others. This is a required step because of signature mismatch between F-Droid and Google Play variants. If you need to back up data before uninstalling app, you can use suggestions from https://wiki.termux.com/wiki/Backing_up_Termux
