[UPDATE & GOOD NEWS]
I did a new install from the 2019.2 version in wamp 64. I guess my uwamp was a bit old. I have imported my database from the previous install, everything did well. Then I have updated with 2023 version and have applied the sql patch. Several errors due to foreign keys in the invoice_item_tax table related to invoice_items table have been solved as I have deleted them. Made the update, everything is well and I have the 2023 version ! The design is not broken anymore.
