IntelliJ Idea 2021.1 Exception Loop during Startup

OS: Windows 10 IntelliJ Version: 2021.1, Build #IU-211.6693.111, Built April 6, 2021

Looks like the plugin is keeping IntelliJ Idea 2021.1 from starting up, throwing an exception. Disabling / removing the plugin allows the program to start correctly (sans the plugin).

Note: Handy command line switch for loading the program sans plugins is “idea64 disableNonBundledPlugins”

Guess this what I get for updating my IDE!

No idea what’s going on. Given that you’re seeing issues with 2020.3 (which has been in use for months), it really seems like something local to your machine. There’s not a whole lot going on in ProtoBaseLanguage that is apparently failing to initialize, which also leads me to believe it’s a platform issue and not necessarily specific to this plugin.

Can you try running IntelliJ with a clean environment? I.e., no plugins, config, etc. There’s some documentation here about how to specify different system and config paths.

Followed the above link, and got a success with a clean config/system/plugins directory. Added plugins back in one-by-one.

Figured out that one of the plugins that was installed was incompatible: “Protobuf Support”, which I thought was a required plugin as it was recommended by the IDE itself. After removing that, all is well.

Thanks so much for your help here!
