Good Afternoon, Good Evening and Good Night!

In the following chat I’ve tried to regenerate 4 times and it keeps failing at the same point.  
chat dot openai dot commercial slash share slash 67264371-7f47-48d8-bb75-5dbb55d29778

I opened a fresh chat and it halts at the same point.  
chat dot openai dot commercial slash share slash ee88a4e1-55da-4be2-b2fb-1167ff61236d

This is approximately the expected output

```auto
public class ExceptionPrintInjector extends Transformer<TransformerConfig> {

    int injections = 0;

```

This is where it hangs

```auto
public class ExceptionPrintInjector extends Transformer

```

Might anyone know how I can solve this issue? Or can this be inspected by the debugging team? There must be some error ocurring during the process of creating the next token at this point. I assume there would be a way for some employee to see what happened in these chats.

I’ve seen another bug report that also talks about the \< symbol causing weird issues.

I appreciate any help or reply!

Have to warn GPT to replace all the ‘\<’ and ‘\>’ with ‘/’ at the top of the input, and you have to replace it manually afterwards, it’s the only way i know to make it generate some codes at least.
