老师，我看了一下`enricher(gson)` 和 `GSEA(gson)`，没有发现来回倒腾的情况。

`GSEA()` use the user defined annotation and `gseKEGG` use the online KEGG annotation.

Please provide repeatable code with the data.

The code works well with me, did you use the latest version of `clusterProfiler`? 

Please try the Github version. If you still have this error, please send the data and the complete code to my email: [email protected].

It is important to provide data to reproduce this error, because many errors have nothing to do with the code.

You should use `enricher()`, see https://yulab-smu.top/biomedical-knowledge-mining-book/universal-api.html#msigdb-analysis

It works well with me: 

> sessionInfo() R version 4.2.1 (2022-06-23 ucrt) Platform: x86_64-w64-mingw32/x64 (64-bit) Running under: Windows 10 x64 (build 18363) Matrix products: default locale: [1] LC_COLLATE=Chinese (Simplified)_China.utf8 LC_CTYPE=Chinese (Simplified)_China.utf8 LC_MONETARY=Chinese (Simplified)_China.utf8 LC_NUMERIC=C LC_TIME=Chinese...

This has nothing to do with the version of the software, you should check that you have executed your code correctly.
