Launch Orange3 core dump for any >3.17 Updated to 3.19 using Anaconda navigator, from CLI I receive these messages

orange-canvas
realloc(): invalid old size
Aborted (core dumped)

python3 -m Orange.canvas
Segmentation fault (core dumped)


Using Anaconda navigator got this log

/home/davide445/.anaconda/navigator/scripts/orange3.sh: line 3:  8261 Aborted                 (core dumped) orange-canvas &gt; /home/davide445/.anaconda/navigator/scripts/orange3-out-1.txt 2&gt; /home/davide445/.anaconda/navigator/scripts/orange3-err-1.txt


Same problem with 3.20.1 or 3.18, is working using 3.17. Working on Kubuntu 18.04 LTS.
Any suggestion for troubleshooting, many thanks.
I have the same problem as you, and I just used pip to reinstall the 3.17 version.

pip install Orange3==3.17
