My son has failed his second year of uni twice

My 23 year old son has just confessed that he has failed his second year of Uni for the second time. He managed the first year fine. The first time he tried the second year, he couldn’t handle the lack of routine during Covid and the second time he took the second year ie last year, he felt anxiety and suffered panic attacks about the invasion of Ukraine. He has spent what I thought was his third year of uni in halls paid for out of his savings leading us to believe he was managing and completing his third year. He is unable to say what support the uni offered as he stuck his head in the sand. I am waiting to hear back from the uni to see if they can reimburse any money for the next term’s housing costs and also to try to work out what went wrong. I feel shocked and hugely anxious even tho I knew something was wrong. He has lied three times about educational progress - the first time about a history a level he was studying for, the second time about not completing his covid year and now this last year. He obviously cannot handle failure and cannot ask for or accept help. Anybody experienced anything similar? Thanks.
