Hello!

At this time I have no idea for possible reasons or actions to reproduce.

Hi!
Thanks for report!
This exception looks very strange to me - it points to problem inside ArrayList's methods. I have no idea how is this possible, only threading issue comes to my mind.
How often does this problem appear?

First and the only time today. PhpStorm near a moment of this exception reported me about 2020.3 upgrade. I'm not sure when exactly this exception happened: before report about available upgrade or after. I did ignore upgare notice temporary and continued to work as usual. Few time later when I want to accept upgrade, I have seen an (!) icon in PhpStorm's right bottom corner. I don't know how long that icon was there.

Hello.
This error occurred once just now. I almost 100% sure this did not happened to me since previous report above.
Plugin version is 2.6.0, IDE version is 2021.2.1.

Well, then such strange things happens, it can be async problem as you guess.
