PARTITION PROBLEM ON MAC

1. I created a partition on my Mac for ubuntu

2. I created another partition SWAP for ubuntu

3. everything went okay

4. I decided to eliminate the partition but I only deleted SWAP

5. I restarted the Mac and now I cannot boot the Mac partition anymore

I tried looking to the internal ssd with a Mac OS installed on a pendrive and the partitions don’t exist anymore, but clicking on the ssd with disk utility it’s possible to see two maps.

using the disk utility in Ubuntu there is also the partition that I tried to remove, saying that the space isn’t allocated. + The Mac partition is not mounted.

There is a way to access to the file in the Mac "partition"? Or to resolve the entire problem and login to the Mac part?
