Almost the same !!! Just one diffference, I use Quest 3. Now we have to wait until META solve the problem!!! No way!!! As above “META lost my respect!!!”
Hey everyone, I tried a quick fix and it’s working like before.
Here’s the tutorial: Reddit Link.
If you want the step-by-step video, it’s here: YouTube Link.
Just follow the video exactly and enjoy! Tested and approved!!

Thank you!!! 
Suggestion to everybody: go to
communityforums.atmeta , find “MSFS 2020 crash to desktop with new oculus driver” and ask/demand for a fix.

I went back to Meta Runtime v57 for now
How does one do that? And why back so far?
Thanks. Mixed results. This effectively rolled back the desktop client and I was able to launch into MSFS with Toolkit. However Link will not launch into its UI. Thoughts?
Buddy happened to have a v57 copy and I blocked ports from updating.
Update. During all of this troubleshooting I had changed my video codec in oculus debug to H.265. This was causing the oculus link splash screen to hang. Setting it to H.264 fixed it. I can confirm that all works very well again in MSFS with quest 3 using link and toolkit following your guidance. Many thanks.

I just leave ODT codec at default and it automatically switches to h.264 with Link and h.265 with Air Link. The only thing I need to do is change encoding bitrate. I use 650mbps (copy/paste) with Link (not that much difference using 500mbps) and 0 with Air Link (then set to 200mbps Dynamic with meta-link dashboard far left icon). I don’t bother using the unsupported OpenXR Toolkit addon anymore btw.
A post was merged into an existing topic: Meta Quest Pro (Officially Announced)
Meta’s developers have released a patch that fixes the compatibility issue with the OpenXR Toolkit.
I recommend participating in the public test channel v68 to install the hotfix.
On behalf of the MSFS community I would like to thank the developer of the OpenXR Toolkit for assisting the Meta developers in resolving an issue with their application.
@mbucchia Your help was invaluable and greatly appreciated.

I’m sure that hotfix will be applied to the non-PTC very soon. I’m not sure whether or not you need to switch your headset into PTC. I think you may only need to do this with the meta-link pc app setting/beta tab. If so, that would be better because it’s a lot easier to switch back and forth from beta to non-beta on the PC app.
My Meta/Oculus PC App just updated to 68.0.0.474.361 - is that the hotfix?
How did you get it to push an update?
I just checked mine (meta-link app non-beta) and its still on 68.0.0.433.361 so maybe you’ve got a newer one that includes the hotfix and it hasn’t rolled out to me yet.
Thanks, I appreciate all your messages here and on reddit to send users in the right direction every time!

yep 68.0.0.474.361.
So join beta.
You’re very welcome.

Ya, simply selecting beta (settings/beta tab) is the easy way to get this. Thanks.
Edit; My non-PTC/non-beta just updated on my QPro (v68.0.0.507.364) and meta-link pc app (v68.0.0.474.361). All’s working very well with my QPro/rtx4090 using Link (without OXRTK). Actually seems to work slightly better but it might just be a placebo thing, lol!

Not sure if related,
Running QuestLink Version 71.0.0.167.524 (with beta enabled), 80 hz refresh on a 4080 (with NVidea drivers 561.09), am I still running into the issue where the headset will randomly freeze (and crash), forcing me to restart the headset.
MSFS2024 still tends to chug along after a momentary hanging.
(Getting to the point, I’m fed up with Mark ####erburgs lack of quality products)
