Sorry to bother you again :)

now, I installed gnuradio on my Orange Pi Zero 3 and tried to run the script headless by changing it to 'No GUI' in the options panel and exporting it to a .py-file. It certainly runs on the OPi and doesn't give any other errors than on my Linux Mint machine but there's no MPX generated. On my desktop machine the .py-script runs perfectly fine! Any help would be greatly appreciated!

System: OPi Zero 3, 2 Gb ram, Allwinner H618/Debian bookworm server, Linux 6.1.31-sun50iw9 kernel, ARM64; version 1.0.4 (Orange Pi release)

Edit: Maybe different python versions are a problem (3.10.12 on desktop vs. 3.11.2 on opi).
