After doing a fresh install of windows and planning on building up V5 with Addons with V5 installers only I've gotten to the point off tuning. AS usual this process starts out at KSEA. Well as I had seen reported else where KSEA appears problematic and CTD's there where definitely worse there than I had generally experienced since V5 was release. All I have installed in ORBX, FSDT, FT, FB, DD all of which have V5 installers. Installing ORBX I basically installed Central 1.4.6 and set up a library outside the sim. I then picked a region to install from scratch letting Central setup the library and paths. I then copied and pasted the rest of my backed up ORBX stuff to the p3dv5 folder in the library and "verified files" for each of them. Bingo all don for now. Anyway, when I was adding the ORBX addons very quickly to the addons at sim starup the word Vector caught my eye! Indeed it was active in addons and after deactivating it I was having a mcu better time of it in and around KSEA. Every time I took of from KSEA I ended up with a CTD. Since unchecking Vector in Addons I've had 2 flights in and around KSEA and landed and shut down the sim normally.

Check your addons list and make sure Vector is not in there. If it is deactivate it. By all accounts its not compatible and I'll speculate it cause CTD's

Also, I'm pretty sure that in ORBX central under my products for V5 the list only shows your products that are confirmed V5 Compatible. So you may well have ORBX addons active in the scenery library that are not listed in Central. I have. As mentioned above. Also Australia is not on the compatibility list. V2 is. We all now what that means 🤣. Anyway, I am going through the compatibility list and cross referencing with the addon list in V5. So far I've found 2 which shouldn't be in there.
