Impossible to make a Time Machine back up

I have a key usb 32 go, I had made a time machine backup on October 21 (the last) which worked very well. but the disk was full so I erased it and tried to start a new backup. Except I don't know why I'm no longer able to save first there was always a message that said she wasn't able to save I don't know which file (it was all day a different one) but now it says I can't try to backup anymore because the disk is not available? Is it well connected though? What can I do? I absolutely have to make this backup because I have to sell my mac.

MacBook Air 13″, macOS 12.6

Erase and reformat a storage device in Disk Utility on Mac

The issue maybe that the " I have a key usb 32 go " does not have a large enough Drive Capacity.

Since a Time Machine Backup was last performed on " October 21 " . the Time Machine Backup has been making Snap Shots to the Internal Drive.

October 21 to November 1 = 11 Days of Snap Shot have accumulated on the Internal Drive and now when you try to Backup - the Destination Drive ( " I have a key usb 32 go ) is just too small

Think you need a Bigger Drive Capacity Drive to achieve this Backup
