Hi,

I have just upgraded on my ubuntu 22.04 server all elastic stack to 8.9.2 from 8.9.1 and now I can no longer log-in because I get these errors:

```auto
Refused to execute script from 'https://kibana. ******* /login?next=%2F64802%2Fbundles%2Fplugin%2Fsecurity%2F1.0.0%2Fsecurity.chunk.2.js' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled.

```

```auto
ChunkLoadError: Loading chunk 2 failed.

```auto

```

How do I fix this?
