Beaver Builder on PHP 7.4 with Give Donations

When I upgrade my wordpress website to PHP 7.4 I am not able to Launch Beaver Builder to edit pages. I get a server error. Turning off my plugins one by one revealed that Give Donations plugin was the one corrupting Beaver Builder. Is there a fix? If I revert back to PHP 7.3 Beaver Builder launches with no problem while Give Donation is activated.

What error is logged on the server? what version of givewp?

I found it was a plugin causing the problem. I disabled it and BB works ok.

What plugin was it? So people know
