Okay I found a solution for you.
I removed pluma and other files completely using synaptic package manager and then downloaded pluma latest version .deb file from here:
https://pkgs.org/download/pluma
I then installed the .deb file using Gdebi and then did a reboot. Now pluma works perfectly even with general icon click and terminal both.
Hope This Helps You Out!!!
For me, I updated the file using apt full-upgrade. After the upgrade I always reboot. I tried using pluma again and it said starting pluma but after some time nothing happens.
The only way pluma runs is using root terminal.
How to access the firejail profile for pluma? And I tried both using menu and using non-root terminal to run pluma. Both didn’t work.

Pluma is not launching anymore. Please help
This cannot be fixed in this way. I think the problem is in configuration. So pluma failed to find $PYTHONHOME, I guess this is the root of error. But the case is python path has configured well. which python returns the correct path

Mine is also the same. It only opens when you are in a root terminal. Reinstalling fixes the problem temporarily but after some time its back to square one.

Got the same pluma error after I upgraded ParrotOS.
Here’s the solution :
That’s it.
Works like a charm, thanks rumytaulu !
OMG Thank you so much. I reinstalled Parrot almost 3 times because of the error.
I use parrot-security
try to dist-upgrade the system, many things were fixed recently
I have the same problem with Pluma.
I reinstalled Parrot with the latest version and Pluma started up directly, but after sudo apt-get update && sudo apt-get dist-upgrade Pluma doesnt launch.
Does anyone have a clew what to try?
please try
sudo parrot-upgrade
The problem has fixed now. If not working please run pluma from terminal and post what output you get
Yep, got Pluma working again! 
i am husing parrot home and after trying to follow the step provided by rumytaulu i was still not able to launch pluma.
i can still use it with sudo tho.
this is what i get when launching from terminal
$pluma

Switching to pid 2854, the first child process inside the sandbox
Child process initialized in 9.03 ms
Wow, so simple, yet, who knew? thanks.
Here is the way I did it. Open terminal, use “sudo geany”. When geany opens, Hit the “File” link, top left, then pick “open”. Find etc/firejail/pluma.profile and open it. Then follow the instructions by rumytauly starting at step 3. Don’t forget to save before you close it.
thanks man your way did work thank you very much
will confirm that I had the same issue, and this fix worked for me. I’m running parrot 4.6 64-bit. Still have issues with libreoffice though…
Pluma did work using sudo, did not launch as a normal user initially. All packages are up to date, running latest currently available parrot 4.6 build.
Launching from terminal gave the usual output up to “child process initialized…” with no apparent error messages, but pluma never came up. Process status is “zombie” in mate system monitor.
Pluma has/had no problem launching as root, or with sudo.
Implemented fix as suggested by rumytaulu, issue resolved.
Can and will confirm issue is still NOT RESOLVED without fix stated above in ParrotOS 4.6 Security edition as of the date of this post.
