Hi Pierre,
There cannot be a "fix" to make the existing Laserfiche Office Integration compatible with the new "Outlook for Windows", as it completely removed support for COM add-ins. The Laserfiche Office Integration is a COM add-in. There's nothing we can do to make our COM add-in work with something that doesn't support COM add-ins.
We had to write an entirely new Outlook add-in that's not based on COM. As the "Solution" section of the KB you linked says:
Laserfiche does offer a new dedicated Laserfiche for Outlook add-in that can be installed from the Microsoft Add-ins Office Store and is compatible with newer versions of Microsoft Outlook 2019 and 365 as well as the new Outlook for Windows. The Laserfiche for Outlook add-in currently supports Laserfiche Cloud, but support for self-hosted Laserfiche may be added in the future. If Laserfiche Integration in Outlook is critical for your business, we recommend that users do not upgrade to the new Outlook for Windows at this time. Laserfiche Cloud users that have the Laserfiche Office Integration, also known as Office plug-in, installed should plan on migrating to the Laserfiche for Outlook add-in. Information on how to obtain and install the Laserfiche for Outlook add-in can be found here:

No firm dates on that coming to self-hosted yet. Using it with self-hosted has dependencies that are not yet in place.
Do you have self-hosted customers who are actually planning on switching to New Outlook at an organizational level any time soon? The general impression of its feature set as of a few months ago was borderline beta software. Microsoft is supporting Classic Outlook "until at least 2029".
