Works fine on latest android 15 avd.

Termux application version: latest

latest is not a version. Generate a report and post.

Issue is likely phantom process killer.

I have this problem too
termux-report_issue_from_transcript.log

TERMUX_APP_PACKAGE_VARIANT: APT_ANDROID_5

Read the installation docs again.

TERMUX_APP_PACKAGE_VARIANT：APT_ANDROID_5

再次阅读安装文档。

But it still says Killed.

termux-report_issue_from_transcript.log

Disable phantom process killer as mentioned above.

Seems like you already have.

Generate a full system log right after process gets killed.

I executed this command, but it had no effect:

adb shell "settings put global settings_enable_monitor_phantom_procs false"

The result of this command returns false

adb shell "settings get global settings_enable_monitor_phantom_procs"

libc    : Fatal signal 6 (SIGABRT), code -1 (SI_QUEUE) in tid 6273 (init), pid 6273 (init)
libc    : crash_dump helper failed to exec, or was killed
linker  : error: unable to open file "/data/data/com.termux/files/usr/bin/bash
"

There is unexpected newline at end of bash path, might be related.

But your logs didn't contain execution history. Exit termux, then run adb shell "logcat -c", then restart termux again and wait for killing and then generate log again.
