Whenever I start VS Code on Ubuntu 18.04 LTS with the Arduino Plug installed, I get the same error multiple times:

Additionally I have to input the password for my account as many times as the error occurs with the message

I've had the same issue with Kubuntu 18.04 when launching Umlet this morning. It appears to be caused by an unattended security upgrade for the openjdk packages.
The answer by rdrever to this askubuntu SE question fixed the error.
Quoting the fix:
This can be done by editing the accessibility.properties file for OpenJDK:
sudo vim /etc/java-8-openjdk/accessibility.properties
Comment out the following line:
assistive_technologies=org.GNOME.Accessibility.AtkWrapper
Hope this helps.
The solution by @Shmukers posted above solves issues related to other software as well. I found this via Google while searching for help resolving this issue when attempting to run Netbeans on Ubuntu 18.04/Mint 19.
@JulianAssmann do you have a try the solution ?
Running on OpenJDK 11 the file is
/etc/java-11-openjdk/accessibility.properties
I just installed arduino in ubuntu 18.04 - I see this error.
In the file /etc/java-11-openjdk/accessibility.properties I commented the only line
assistive_technologies=org.GNOME.Accessibility.AtkWrapper
and arduino started the ide.

Is the accepted solution not working for anybody else? (Kubuntu 20.04)

Try to find another accessibility.properties file in the system.
