Getting errors: (subscription trial end) failed to finish processing

Hi, this plugin appeared to be working as it should, but when the day of our selected first payment date came we started receiving error messages for all pre-orders placed. Any help or insight into the errors included below would be much appreciated.

In the wordpress admin it shows:

An error has occurred while processing recent subscription related events. Affected events:
subscription trial end for #15233
subscription trial end for #15221
subscription trial end for #15201
subscription trial end for #15268
