Cannot boot after restoring to new SSD | macOS Mojave | Acronis2019&2020
I have a MacBook Pro 2015 running the latest macOS Mojave. Having purchased a larger SSD, I used Acronis True Image (ATI) to move the entire disk's partitions and content to the new SSD. Since I do not have the means to connect the new SSD to my computer externally, the Disk Cloning option is not for me. I made a backup with the original disk and went on to restore the backup with an Acronis Recovery Media pen drive, after switching SSDs. Although the image was created using ATI 2019, I used a Recovery Media made with an ATI 2020 trial to restore, so I could avoid the hassle of using scripts as described here: https://kb.acronis.com/content/60425. The restore indicates success and I can verify that all partitions are created in the new SSD, as expected. However, when I restart the computer, I get the flashing question mark folder, indicating there is no bootable device. I try to resolve the situation following the advice in the section "If your Mac doesn't start up" of this Apple article: https://support.apple.com/en-us/HT204323. The "Macintosh HD" is listed correctly in Startup Disk, however, when I try to restart from the selection I get the message "You can't change the startup disk to the selected disk - Building boot caches on boot helper partition failed". I attach an image of this. Please note that the new SSD works perfectly. I can make a fresh install of macOS on it and everything runs with no problems. But what I need is to transfer everything from the old SSD to the new one. I have been trying to get help from Acronis Support since the 11th of September, but it's taking ages. Only a week ago I got past the first line of support (with a technician that gave me a lot of standard information I already had) and I am waiting for a reply from a team of experts (mentioned by the support technician) since then. Can anybody help? I can post additional information if required.

Did you send the feedback with system report attached from bootable media after recovery?
If you did, please, let me know, I could ask the development team to check what is wrong.
I sent, as requested by the support technician: 1 - System report collected from the bootable media; 2 - Error screenshots; 3 - Recovery log collected after the recovery completed.
I still have no reply from the team of experts or the support technician himself.
