React Native - TypeError: window.addEventListener is not a function (it is undefined), js engine: hermes

Question

I have an expo project, and setting up a clerk auth. I have followed all the required code clerk gave, and now getting this error on the links. Everything looks okay to me, but I cant figure out how to solve this issue. Im not building a web page, and i dont have addEventListener in my code anywhere. I dont know why is this happening.

with this folder structure:

I also had this issue and found this reply from the clerk team on a discord channel:

"This is a known issue in our latest version of @clerk/clerk-expo and we have a patch coming out in the next release.

For the time being, we are advising users to use version 2.2.5 where this issue is not present.

Apologies for the inconvenience here but please let us know if you have any other questions!"
