I Updated to Mac OS Sonnoma and FCPX 10.6.10 AUDIO PLUGINS NOT WORKNG

I Updated to Mac OS Sonnoma on my Mac Mini M1 and FCPX 10.6.10 AUDIO PLUGINS NOT WORKNG. All my plugins, UAD, iZotope, Soundtoys, Cableguys, work in the new Logic on Sonnoma just fine.

I went back to my other mac mini 2018 intel thats still on Mac OS Monterey , I copied the FCPX program and installed it onto this computer, however when I try to open one of my librarys it says that this library was creatted in a newer version of FCPX.

( I have 2 Mac Minis, One is for video editng (the m1, the 2018 intel is for recording studio)

I downgraded to that FCPX 10.6.5 that was on my old mac and FCPX validated all of my audio plugins and IT STILLL gave me the same validation probelms, expect this time it found more plugins it dosnt like like fab filter, etc so the problem is either with the Sonnoma or the new FCPX support for Audio Plugins such as Native Universal Audio Plugins, CableGuys Pancake plugin, iZotope Ozone 9 Advanced, iZotope Relay, iZotope Total Balance Control

My first question: IS THERE A WAY TO KNOW WHAT VERSION OF FCPX with the .fcpbundle library / project?

My Second Question: How can I download that version of FCPX I had if the newest one will not work with my audio plugins and the one from my other mac 10.6.5 is too old? I'm guessing I was on 10.6.6 or 10.6.7 but how can I know? I don't have a time machine backup of when i was on Ventura unfortunately.

WHAT SHOULD I DO? I HAVE ALL MY FCPX FILES SAVED ON A SSD EXTERNAL BUT DON'T HAVE A BACKUP. SHOULD I TRY FIND THE FCPX VERSION AND DOWNLOAD IT FROM A WEIRD SITE OR SHOULD I TRY TO WIPE MY DRIVE, DOWNGRADE TO VENTURA AND HOPE THAT FIXS IT? I WISH I NEVER UPDATED FCPX AND MY MAC OS WITHOUT MAKING A TIME MACHINE BACKUP FML
