Plugin error in 4.21 on iOS "immediatePhysics"?

I updated my project from 4.20 to 4.21 and did some minor changes, packaged it and I’m getting this error when trying to open the app.

I don’t know if its something I did or the engine. I can’t find anything about this and I’m not sure how to fix. I tried verifying the engines files and repackaging, but that didn’t do anything.

Alright I fixed it. All I had to do was delete the app on my phone and repackage because the app was for the older engine version. I also deleted the saved/intermeds/build folder, but I think that was unnecessary.

Thanks, had the same problem and this helped.
