I’m not sure if this helps you, but rolling back to version 2.9.1 resolved the issue for us. GiveWP initially suggested that there was a conflict with some plugins but disabling them did not resolve the issue. It was only resolved when we reverted to the prior version of GiveWP. When I contacted them last week about a different issue, they mentioned that they are working on a patch but I’m not sure if that would help you. Good luck!
