resolve 15 not startin on linux (TO BE CLOSED)

Hi all,
i am a new user here but i use davinci resolve since a couple of years.
I own a linux workstation, with Arch.

Installation and configuration went fine, even though i've always seen resolve a bit unstable, so i do not upgrade very often.

yesterday I did...and puff...davinci does not start anymore.

I know i can rollback upgraded packages, but since 17 is now available i would prefer to install the new version.

Can anyone help me understand how to copy the old database files and import in the new resolve?
Thanks

Maybe u could post a link to the logs to help repo the crashes? Details in FAQs
