I’m publishing an android app using Unity 2019.3.9f1. When I build I get the following message:

UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)```

This has never happened to me before, and I'm not really sure about what I did to get this error. It was compiling fine before, then I switched to iOS builds for a couple of weeks and now I've been getting this error message.

Is there something I can do to fix this error? Googling didn't help me much. Thanks!

This is my editor.log file if it can offer any insight.

It’s complaing about Temp/StagingArea/Data/Managed directory, maybe it’s locked. Try closing Unity and delete Temp folder if it’s present

Sorry if I haven’t replied for a while… the Temp folder was misteriously impossible to delete but I’ve finally managed and now it’s compiling properly. Thank you so much!

@man-teiv How did you solve it? Still bashing my head against the same problem.

I had to close dropbox for it to stop messing with my temp folders, guess you arent using dropbox tho.
