I have downloaded the Arduino IDE 2.0.2 as appimage for my Linux PC.
After setting the file "arduino-ide_2.0.2_Linux_64bit.AppImage" as executable, I tried to double-clik on it to start the IDE, but nothing happens...
Same result from the CLI: no error messages, no printouts. The prompt appears back, but the IDE doesn't start...
Are you using a very old version of your Linux distro (e.g., Ubuntu 16.04)?
This error occurs when you have too old a version of the IDE's libstdc++ dependency installed on your computer. If you are able to update your distro, that would probably fix the problem. If not, I see some instructions for updating libstdc++ here:
That seems not the problem. An updated library is already installed...
$ sudo apt-get install libstdc++6
Reading package lists... Done

Reading state information... Done
libstdc++6 is already the newest version (5.4.0-6ubuntu1~16.04.12).
The following packages were automatically installed and are no longer required:
jq libcoin80v5 libonig2 libpdf-api2-perl libsoqt4-20 libwireshark11 libwireshark12 libwireshark13
libwiretap10 libwiretap8 libwiretap9 libwscodecs2 libwsutil10 libwsutil11 libwsutil9 python-qt4-gl sane
wireshark-gtk
Use 'sudo apt autoremove' to remove them.

I think if you build Arduino IDE from source then it would. The dependency is based on the machine used for the build. The builds distributed by Arduino are made on a machine running Ubuntu 18.04. This older version is used even though newer ones are available specifically to provide support for older distros (but not so old as yours):
Unfortunately building the IDE from source is a somewhat advanced endeavor.
Uh!
I forgot to check the solution published on askubuntu.com... shame on me!
I will try it tomorrow... now I need a bed and sleeping for 256 =2^8 hours (as minimum).
