# Description

When I double-click on `processing.exe`, the logo window of Processing shows up for a couple of seconds and then it disappears.

# My Environment

Processing version: 3.4  
Operating System and OS version: Windows 10  
Other information: 64bit, 16GB RAM, 4k display plus HD display, but also tried with single HD display.

Starting with Processing with `--l4j-debug` produces the following log file.

```auto

```

After enabling debugging information, I get the following in the `console/*.out` file:

Clicking on an example `.pde` file changes the last line of the preceding log into the following sequence, but again the IDE fails to appear.
