Super slow loading into the sim/ loading up a flight

Brief description of the issue:
2-3 Days ago i went to start up MSFS and then all of the sudden it took FOREVER to load, im talking 15-20 minutes to get to main menu. So i thought there was an issue with the sceneries I installed, but when i removed the sceneries (there was a couple i downloaded from flightsim.to) the loading issue persisted. And then all of the sudden my X-Plane would take forever to load as well, and then it would perform poorly all of the sudden and crash. So i uninstalled BOTH sims, and reinstalled them, the issue with MSFS2020 is the loading issue. It takes forever to load, I literally just got finished with DBAN’ing the SSD I use and RESINATLLED MSFS2020 for the 2nd time in 2 days to make sure that the drive was clean from any sort of data being on it… and i installed MSFS2020 and then it still takes 10 minutes to load into the menu from a vanilla installation… I timed it… 09m13.65s to load into the menu from my desktop, so im not sure if anyone else is having loading issues like I am, but if so please help me out because this is super frustrating. I opened a ticket with Zendesk and im in the process with them as well. I did one of their recommendations to see if there is any corrupted files onboard my PC, and it turns out there was but there was a program that fixed them. Im not sure what I should be doing honestly, or what is causing/ caused my sim to start slowing down like this. Once i can get the sim to run, it runs beautifully otherwise and performs great.

Detail steps to reproduce the issue encountered:
You really can’t is the thing, i think its comes down to optimization. But at the same time i dont think so cause this started happening 2-3 days ago.

Are you on the Steam or Microsoft Store version?
Microsoft Store version

Did you submit this to Zendesk? If so, what is your ticket #?
Yes, Ticket #106278

If you have a lot mod/scenery/aircraft - time for loading is increasing. Try loading without mod.
And SSD drive is required. m.2 NVME best choise

I’m so curious about the console version.
Is Asobo thinking that the console audience can wait 6-7 minutes before playing?

I just experienced this issue. I have no mods. Just the sim as downloaded from ms store.
Just few hours ago, the sim was loading fine. I have no third-party plugins or mods. And now it is taking forever.
It seems to be stuck at the first loading screen with the loading bar at 75%…then 4-5 minutes it loads.
I have pc that can run anything. Just to cut specs short!!
Drivers, game service, windows update, all up to date. Just out of the blue comes this hiccup…Any solution? Cheers
