Updated everything - NOW P.T Crashes / protools wont load my projects

[Seafoam_Green]

Hi Guys, I've been traveling and suffered some personal hard times over the past three years.

Now I've got my gear out out storage finally (that all worked fine before)

.., and now if I try to load my old ProTools projects (and earlier unfinished original works in progress) ...,

- I get a crash ( ie; application quit unexpectedly message window) in pro tools on startup, but otherwise, if I say create a new project pro tools opens fine


Note :

- i updated my OS from Sierra up to Mojave
- I updated protools from 3 years ago to PT2019.6.0
- I updated all my plugins and VI's and their libraries, including Arturia Toontrack, Native
instruments and all the Avid extras etc, making sure nothing was left out.

I am only on the cheaper perpetual plan and not the avid support plan (rant alert; even though you buy their product and its not working you should get support no matter what), so all I can do is send them a crash report but as far as support from them ..., well no support otherwise.

any ideas guys?

also ;

im on a mac pro late 2013 (the trashcan)
mbox pro (latest updates)
pro tools projects on a separate PCIe drive (note I also copied these to my desktop )
backup drives net the same crash results also
