IntelliJ IDEA apex code style not loading after upgrading Illuminated Cloud 2 plugin

[Virginia Barros]

hi!
I upgraded the Illuminated Cloud 2 plugin and after doing that Intellij IDEA stopped recognizing my apex code styles.
If I go to Settings / Code Style / Apex the page keeps on loading and nothing is shown (i attach idea log file)

My environment:
IU-191.6183.87, JRE 1.8.0_202-release-1483-b39x64 JetBrains s.r.o, OS Linux(amd64) v5.4.0-67-generic, screens 1920x1080, 1920x1080

Hi. You're on a very old version of IntelliJ IDEA (191.* indicates 2019.1, I believe). Please upgrade to minimally 2019.3.5, ideally 2020.3.3.

Resolving this assuming that updating the base IDE will address the problem. If you still see issues after updating to 2019.3.5 or 2020.3.3, feel free to reopen and provide new logs.
