It seems that replacing

public function getMessagesGreaterThanUid(string $folderName, int $uid, int $limit)
{
    return $this->getFolderByName($folderName)->query()->limit($limit)->getByUidGreater($uid);
}

in app/Mail/Connections/Imap.php

by

public function getMessagesGreaterThanUid(string $folderName, int $uid, int $limit)
{
    try {
       return $this->getFolderByName($folderName)->query()->limit($limit)->getByUidGreater($uid);
    }
    catch(\Exception $err) {
      return new \Webklex\PHPIMAP\Support\MessageCollection();
    }
}

solves the problem, but I don't know whether that is the right way of addressing the problem.

Having problems with the import here as well. Any chance you could help with my issue #17565? :(
