Termux widget presumably does not start background processes

[freebrowser1]

Problem description
Starting a novnc daemon (https://github.com/novnc/noVNC) to act as a server for web VNC works flawlessly when started from Termux itself, but not in a Termux widget task.
In a terminal it shows output :

 /data/data/com.termux/files/home/novnc/utils/novnc_proxy --vnc localhost:5901
Warning: could not find self.pem
Using local websockify at /data/data/com.termux/files/home/novnc/utils/websockify/run
Starting webserver and WebSockets proxy on port 6080
/data/data/com.termux/files/home/novnc/utils/websockify/websockify/websocket.py:31: UserWarning: no 'numpy' module, HyBi protocol will be slower
  warnings.warn("no 'numpy' module, HyBi protocol will be slower")
WebSocket server settings:
  - Listen on :6080
  - Web server. Web root: /data/data/com.termux/files/home/novnc
  - No SSL/TLS support (no cert file)
  - proxying from :6080 to localhost:5901


Navigate to this URL:

    http://localhost:6080/vnc.html?host=localhost&port=6080

Press Ctrl-C to exit

and indeed works as a web frontend for a VNC server on port 5901.

Steps to reproduce
Create a script in .shortcuts/tasks/novnc.sh which is supposed to be for background processes according to https://github.com/termux/termux-widget?tab=readme-ov-file#Creating-And-Modifying-Scripts and make it executable.

• Contents

termux-fix-shebang 
PREFIX=/data/data/com.termux/files/usr
cd /data/data/com.termux/files/home
/data/data/com.termux/files/home/novnc/utils/novnc_proxy --vnc localhost:5901

• Refresh the termux-widget and click on tasks/novnc.sh.

Expected behavior
Background process should run, the ps -ef should show something like python3 -m websockify --web /data/data/com.termux/files/home/novnc 6080 localhost:5901, just like it were started from terminal.

Additional information
No python3 process is started. I tried with an & behind it and with nohup before it and an & behind, indeed logging to nohup.out. However, doing the same in the widget script does not result in any running process or nohup.out.
Here the logcat output for this script.
