Mail import fail on Ventura 13.5.1
Shut iMac off, went on holidays, came back, turned it on, every worked except the mail. The Mail App tries to load 20G worth of mail and at the very very end, it says import failed. I tried to delete some container files but same thing keep occurring. Tried to download the Mail App but it doesn't let me.
please help me. I am desperate.
