Loading a second pln causes CTD

PC - Steam - 1.19.9.00 - no dev mode - no add-ons

Loading a .PLN file to check if it is correct, subsequently
loading another one, causes CTD.

Mainboard: ASUS Maximus X Hero Intel Z 370
CPU: Intel Core i7-8086K @ 4.0 GHz
Memory: 32GB Corsair DDR4-3000
Graphics Card: ASUS NVIDIA GeForce RTX 3080 10GB

Maybe the “other one” was not compatible, rather than the issue being that it was the 2nd one.

Easy Test… Try loading the 2nd one 1st, and see what happens when it loads, and also what happens when you load what was the 1st one, as the 2nd one …

Also, how are you loading flight Plans … many ways …

If you are still having issues and want help, maybe post your 2 flight plans here for other to try them (and help you)

Hi, thanks, this happens with ANY second one…
And what should be not compatible? All are made inside MSFS planner.
Loading .PLN files.
The only way to load plans I am aware of are loading .FLT plans, and .PLN plans…

OK . Got my attention now – Interesting.

(1) MS-Store or Steam
(2) PC or X-box
(3) If Both flight plans are most basic, (ie Just Departure airport, Destination airport, VFR DIrect – does the 2nd one still cause a CTD ?
(4) Nothing in Community
(5) WT Nxi not installed (Official)

If all above are true, then that is really peculiar, and worth further investigation !!

Thanks. Most of the questions you ask are already answered in my first post.
IFR low with waypoints. VFR basic I don’t have. WT Nxi not installed.
