I am running Civicrm on Wordpress 6.3.1 and today I upgraded Civicrm from 5.58.1 to 5.65.1 successfully with no errors. Log output - [info] Running task: Finish core DB updates 5.65.1
I did notice some other warnings -
[warning] ManagedEntity update policy "unmodified" specified for entity type SearchDisplay which is not an APIv4 ManagedEntity. Falling back to policy "always"

I am not sure if my issues below is related to the above warnings.
#1. I was testing mailings after the upgrade I have noticed that the recipient field was empty (but showing the number of recipients {3 in this case} for a previous draft email). The error that I am getting is "Loading failed" when trying to select another group of recipients.
#2. I tried a new mailing and I get the same error "Loading failed" and am unable to select any group recipients.
In case #1 above the mail does get sent to the recipients.
I have attached a screen shot.
I am running Flexmailer.
Any help would be appreciated
Many Thanks
