And this looks like no clear error shown in the event log...

Then in the "Tasks", I can see message as "Computation Error" after 10 seconds elapsed.

The system info is as:

ERROR: Unable to open file: minirosetta_database/chemical/residue_type_sets/fa_standard/residue_types.txt

A over protective AV programme could be clobbering the files.
I'd suggest putting the BOINC data folder in the exemptions list- then Reset the project. It should then re-download all the files it needs, and be able to start processing again.

It looks as below:
drwxrwx--x. 3 jari jari 4096 May 30 20:15 boinc.bakerlab.org_rosetta
drwxrwx--x 2 jari jari 4096 May 30 08:38 boinc.thesonntags.com_collatz

And the "collatz" seemed to work without computation error...
The dot (for SELinux) then possibly is there, but not sure how it got there.

According to the Filesystem permissions wiki page, the dot indicates a SELinux context is present. Show activity on this post. + (plus) suffix indicates an access control list that can control additional permissions. . (dot) suffix indicates an SELinux context is present

OK. that seems correct assumption and it was fixed by reinstalling the whole MX-linux (and changed from November2021 base to April2022 base).
And it looks the firewall came back and the Rosetta is running now as well.

I think there is some issue, because the all the unfinished tasks were lost during the system reinstallation.
This case the tasks are stored into the /home/user/projects (what I think) and system installation case only the /-partition is formatted and rewritten by the linux installation.
It could be better if the boinc keeps all the files in the /home/user/projects directory, but some of the files were found also in the /home/user directory
and in the /var/lib/boinc-client directory.

The boinc directory as below:
--dir <path> use given dir as BOINC home
Could be set as default to /home/user/BOINC by the boinc installation...
To avoid making it too complicated.
