Auto generation of SHA512 KEY

I am getting intermittent card failure reports.
The payment is being taken but not being reported back to woo commerce so the order it is associated with times out, and is marked as cancelled due to non payment, this is happening once in every 100 or so transactions, and is creating a a real problem as resources are being fully used up and then additional people are tuning with proof of booking,

i have spoken to both woo commence and barcleys and they suggested that all is well at their end so could you look into it please?

errors are as follows:

displayed inside wordpress admin dashboard:

Check compatibility with new version of wordpress and woocommerce

I'm getting what looks like a common error when testing Barclays EPDQ on Woocommerce.
It all seems to go through OK, the Barclays's site says the payment is authorised, but after a few seconds wait it goes to take me back to the website and then goes to this link:
https://www.amadihome.co.uk/wc-api/RapidDive_WC_Gateway_Barclay/
with the message: "There has been a critical error on this website."
I have found a solution from 2 years ago (change 'Default operation code' to 'sale' but this is still happening.
Do you know the best way to fix this please?
Thanks

After selecting the EPDQ payment, an error appears An error has occurred; please try again later on the page https://mdepayments.epdq.co.uk/ncol/test/orderstandard.asp. If you are the owner or the integrator of this website, please log into the back office to see the details of the error.. Nothing is visible in the logs, only BRAND too long : length 27 MAX:25.
