Opening installer on Linux results in a blank white window

[kiosion]

Describe the bug
Opening the Impact Installer in Arch Linux results in a blank window. When opening from a terminal, the following text appears... despite what it says there is nothing being downloaded, it stays stuck here indefinitely.

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

I've tested with OpenJDK 11 and 17, it's the same behaviour with both versions. I've also tested inside an Ubuntu vm on another pc, same behaviour there as well. (Edit: Followed the install FAQ advice, tested with OpenJDK 8 too. No dice.)

To Reproduce

1. Download installer
2. Run with java -jar [installer name] or by double-clicking on the .jar
3. See error

Expected behavior
Installer GUI should appear in the window.
