GA5 SE - Unable to load presets

Cubase Pro 12, Win10 (latest).
When trying to load (inside a C12 project) some GA presets, which were created and saved a few weeks ago, I get a warning saying:

“The preset could not be loaded. This can happen if the preset was saved by a newer version of this plug-in or by an incompatible plug-in.”

Which sounds quite odd, as the presets were saved by GA5 itself and the installed version is the latest (5.1.11).
The message appears both in the GA stand-alone application and in the GA plug-in.
Any ideas about a possible solution?

Related to this?

Probably yes, at least to some extent.
Thanks for the link.
I’ll try to investigate further, also thanks to the information provided by the video.
