While changing the values of a `widget` in `properties` tab, `AndroidStudio` keeps on throwing `IndexNotReadyException`. But after few minutes while retrying, the error is not occurring.

**Here is the error log:**

```

```

I've updated the `AndroidStudio`, to latest one. But still the error occurs. Any fix or work around?
