Hello List,
I'm looking for some help from experienced users, at least more than I. 😉

PROBLEM: I'm facing to an annoying issue I never had before with only one of my projects under development: Simple MIDI Sequencer (SMS) Vanilla. Means my problem could be externals related?
Up to the last days everything was okay, but after a day of modifications I saved a last time my project, and...
Now after having launched Pd Vanilla v.0.53.1 (PPA install) and then opening my project both immediately close automatically (which is not the case with my other projects).

I'm running under Linux Mint 21.1 Cinnamon 64-bit (Ubuntu 22.04 LTS base) and I'm using objects from the following 8 Externals (Deken install):
Cyclone 0.6.1, Else 1.0.0 rc6, Ggee 0.28, IemLib 1.22.2, Jmmmp 0.61.0, List-Abs 0.1.0, PdOgg 0.25 and Zexy 2.4.1 (they are supposed to be up to date).

As you can see here-after "puredata" or "puredata -verbose" are not working BUT "puredata -stderr" is working. Weird, isn't it!

Any thoughts and/or search directions are more than the welcome.
Thank you.

1st Test / Launching from a Terminal => Not working
------------------------------------
joe@mint21:~$ puredata  -or-  puredata -verbose
Pd-0.53.1 ("") compiled for Debian (0.53.1+ds-1~ubuntu22.04~ppa1) on 2022/12/15 at 22:02:06 UTC
float precision = 32 bits
port 34801

.....
Then opening my SMS Vanilla project from with Pd Vanilla immediately closes both Pd and my project.
So, same bad behavior than in my above introduction but now with a "segmentation error" indication!

2nd Test / Launching from a Terminal => Working okay
------------------------------------
Very strange thing here by just adding "-stderr" I'm able to run, modify and save my project without any issue.
Note1: Now the same is also true in pure graphic mode if I'm adding "-stderr" to Pd Startup options, but with no output in the Pd Console.

Note2: In the here-below long terminal output I removed the unnecessary stuff like all the kind of "verbose(4): tried ./cyclone.l_amd64 and FAILED" (about hundreds and hundreds and hundreds of objects).
