Upgrade failed EE 2.10.1 to 3.4.2

Hi,

I tried for the third time to upgrade a website running EE 2.10.1 to the latest EE 3.4.2.

I keep having the following error message during the migration:

Any idea what can cause this issue?

I followed all the steps of the manual: https://docs.expressionengine.com/latest/installation/upgrade_from_2.x.html

Thank you
