Hello,
Questions to the community belong in Community Support. Your thread has been moved there.
Hi guys, I’m new to the forum. Joined this morning because I have the same problem. Please can someone advise me?
After this mornings mandatory update 28/04/2022 I have no avionics at start of flight, no auto pilot, I’m unable to select an altitude and push back is the speed of a crawling baby. Any ideas?.. and please, speak as you might to a young child or a golden retriver. It wasn’t brains that got me here I can assure you of that. 
Thanks in advance.

I installed su9 two days ago and all seemed fine. I installed the Garmin update yesterday and now I’m suffering the same problems. I then uninstalled the Garmin add on completely and set up a short flight to Brussels. All went well until the approach to Brussels then I lost all instrument panels, autopilot and ILS then crashed to desktop. It appears that once again a SIM update has done the opposite of what was intended and has indeed rendered the SIM unplayable.
By the way, welcome to the forum. I should have said that at the beginning.

Thermal really messed up on this update lol
Hey Monkeynuts, thanks for the welcome. 
I have now resolved the issue thanks to user SamuraiSax
Bug Reports / Aircraft & Systems / PC / Aircraft / MS-Store / Avionics not working
Not sure if it applies to you but it was suggested that an add-on PMS50 GTN750 was conflicting with my avionics. So I deleted it from the community folder -
Filename - pms50-instrument-gtn750
Directory - C:\Users\YourName\AppData\Roaming\Microsoft Flight Simulator\Packages\Community
If you can’t find it there, then you might also try -
C:\Users\YourName\AppData\Local\Packages\Microsoft.FlightDashboard_8wekyb3d8bbwe\LocalCache\Packages\
Otherwise it might be worth running the sim in safe mode to see if any add-ons are conflicting.
Hope this helps. I’ll check back to see.
Sorry, I should have mentioned that I am on Xbox and not pc. I am working on uninstalling all add ons and re installing one at a time to isolate the cause. Happy that you found a solution.

My fault for assuming you were on PC. Best of luck. o7
Hello @Sniperpig5 ,
I am on PC and This solution has worked 100% for me. For me, I deleted pms50-gtn750 from community folder, downloaded new version, and placed it back, and now it appears to have fixed it for me.
Just done night fly and all seems ok sop far.
cheers
It was panic stations there for a while. 
Glad you got it sorted.
I have the problem on PC. Everything worked before Update 9.
But a sulution is not in sight. I have to deinstall MSFS and install new.
For me the problem affects some MFDs on some aircraft. I have the sim on windows 10 with the X-Box app.
Not tried all aircraft but cubs & things with old clock style instruments - OK, Cessna 208 caravan - all MFds OK, A320 - all inop (XXXX or blank.) Same with TBM and Extra 330 now has 2 MFDs - both with flight instruments where one is XXXX and the same one beside it works???
Nothing in Community folder to clash (but tried with/without), small G1000 update applied - not helped. Used Content Manager to uninstall then reinstall affected aircraft - not helped. I guess it needs a patch.
(Weirdly though when in my Content Manager I saw a microlight that I haven’t bought - but one paint job for it only, plus a T6 Texan - also not ordered/paid for but incomplete. Deleting these ‘stubs’ results in the sim reinstalling them next startup!!!
I also had sim startup probs at first last week - the usual X-box app comms failure. (Cured as usual by uninstall app, shut down, reinstall (quicker than finding the duff component).
really really weird all of thsi.
I wouldn’t. There will have to be a fix. And 99 percent other sim problems are outside the sim (PC X-box app fails etc).
same here c172 stock all instruments went dark after standing 3 minutes on the airfield with engines on
