I am using the newest (updated) version of IntelliJ IDEA. I am coding in Javascript (React) and i've been using the One Dark theme for ages now. But since the last update, everything is glitched.

So first problem: The IDE is now allways starting in the white theme (which is related to the windows theme) When i try to change the Theme, either nothing happens, or it just doesnt show any Themes, even tho i installed more than 14 (they are disabled tho).

Second problem: I can not code in Javascript anymore. There is just no collor at all. No marking for functiond etc.

Third problem: My IDE is crashing almost everytime, I try to open a new, or existing project.

Why is that, has someone simular issues, and what can i do, to prevent having to reinstall my IDE, as i do not want to set my IDE up again.

Thank you in regards

I've had this problem myself. I tried many things. But in the end, i just reinstaled, and I was good to go.

So i suggest, you try to note down all the important tools, you have addet, and all the themes, then reinstall the IDE, and then just add all the tools etc. back in.
