Hitting Message Limitation Due To Errors

I’m getting some what annoyed, as a GPT Plus subscriber, I should be able to use the platform I’m paying for right? Well I keep trying to engage with my Custom GPT and it error out 90% of the time. It was working well until last week… not I have to press regenerate multiple times, hitting my limit, making it useless…

Not sure what to do here, anyone else?
