Continuos unexpected errors

Unable to proceed, Franz is having unexpected errors everytime I try to send my message and whenever I try to resend it in the options. I've tried to delete it then resend as another message, still fails. I tried to delete the previously created post from Franz and then respond and that still didn't work. I've tried clicking the retry button displayed and the same error pops up. I don't know if this is because the campaign has been going on for so long that it's trying to send everything back and it's too much for Franz to handle, like what chatgpt does.
