[Bug]: termux-camera-photo returns empty file - error in logcat

[Duvio]

Problem description

When trying to take a picture using termux-camera-photo it most often works, but after having Termux run a long time in background, that command stops working properly. Instead of taking a picture and saving it in the provided file, it just writes zero bytes.

logcats output is:
