Looks like my initial analysis is incomplete. What fails is

CryptQueryObject(CERT_QUERY_OBJECT_FILE, "...\\plugins\\action.micl",
CERT_QUERY_CONTENT_PKCS7_SIGNED_EMBED, &store);
do ((cert = CertFindCertificateInStore(store, prev)))
{
    if (prev) CertFreeCertificateContext(prev);
    prev = cert;
} while (cert);
CertCloseStore(hstore); // <= assert()

This is what https://gitlab.winehq.org/wine/wine/-/merge_requests/10439 is
supposed to fix. It seems that this behaviour is specific to PKCS7 store.
