@AlexPl292 I see ide.slow.operations.assertion=true. It can be safely set to false (Help | Find Action | Registry | then toggle ide.slow.operations.assertion).
I will try to rework the way I query the IDE filename index, which should fix this issue even if ide.slow.operations.assertion is enabled.

[jonathanlermitage]

Found a solution, but it requires IDE 2023.1.

• I will release Extra Icons 2023.2.1 without this fix (but, with support for old IDEs). This is a big update.
• Extra Icons 2023.2.2 will include this fix, and it will require IDE 2023.1 as the new minimal supported version.

So, for now, the workaround is to disable ide.slow.operations.assertion, which should actually already be set to false. I think this is set to true in EAP and RC builds only?

Also added some documentation: https://plugins.jetbrains.com/plugin/11058-extra-icons/errors-workarounds

Hi, thank you for the fix! As I know, yes, it's for EAP releases only, but it is supposed to be enabled for all releases at some moment.
