SIOC Access violation on Win 10

Hi All,
Hopefully, this is the right place for this post.
I have the open cockpits MCP3 & EFIS, they used to work fine with the Oi4FS which uses SIOC. However, I haven’t actually used it for probably 6-8 months or so, now when I run SIOC by itself, as it opens it generates an access violation at some address, so I can no longer use the MCP or the EFIS.
As I say, it has always been working but I have had some kind of Windows update that now it crashes. I have a laptop with Win 10 which has been off for the last 6 months and therefore has not had any Windows update, I can run SIOC on the laptop with no issues, so it seems to be the main FS2020 PC which has had some kind of an update that is causing the problem.

I wondered if anyone else has had this issue and if there is a workaround for it.

Thanks,
