I think I found the issue on my side....
So basically I found the following entry
Phone Validation Regex Pattern: ihfhwifhwikhfowhfuowhfuiwhfuiwghfiuwhfhuwfh
I have then changed it to this: /(.*?)/
As per the AbanteCart doc on regex
So saving the config to use this resolved my payments issue "/(.*?)/

I have then reverted the regex, and the payment option disappeared again.
