Debugging remotely on a Raspberry Pi 4 with Boot2Qt 5.15.10 raises an error for GDB. Debugging still works, however, Qt types such as QString don’t show their stored values.
The error shown in the attached picture.
Running GDB and executing import sys; print(sys.version_info) in the runtime environment confirms having a supported Python 3.x version (sys.version_info(major=3, minor=8, micro=12, releaselevel='final', serial=0)).
The issue does not appear in Qt Creator 14.
