Dynamics Community Forum Thread Details

This is a heads-up to Microsoft and anyone planning on deploying the latest Update 1.25.
On patch tuesday 14th of february Microsoft released Service Update 1.25 for Microsoft Dynamics CRM (on-premises) 9.1/ for on-premise deployments under KB5035110 (v9.1.25.17)
I noticed yesterday when checking that this update was gone but today(29th of february) a new release of this update was available KB5035110 (v9.1.25.19).

As I usually do when new updates are available I install and verify them in my test environment, which I did with the first released update of Update 1.25 without any errors or issues during install or with the environment post install.
However I today tried this new released version and basically nothing is working, e.g. AsyncService is crashing on start along with the Dynamics 365 Web(w3wp).
They throw the following error

AsyncService:

I have checked and this Microsoft.Xrm.RemotePlugin.Common.dll was updated in the latest release v9.1.25.19 .
I've tried both replacing it with the one from prior release v9.1.25.17, that throws a new error.
I've also ran a repair on the Dynamics 365 installation for good measure but yeah, same error which sort of was expected.

I hope this reached someone in the D365 team at Microsoft, but for anyone planning on upgrading to the latest Update 1.25 I'd suggest you hold for a bit.
