The original and the many amended versions:
The original Virginia Constitution of 1776 was enacted in conjunction with the Declaration of Independence by the first thirteen states of the United States of America. Virginia was the first state to adopt its own constitution, and the document was widely influential both in the United States and abroad. In addition to frequent amendments, there have been six major subsequent revisions of the constitution (in 1830, 1851, 1864, 1870, 1902, and the one currently in effect, in 1971). These new constitutions have been part of, and in reaction to, periods of major regional or social upheaval in Virginia.
Seems like it evolved and added amendments to handle things. Some of the evolutions paralleled things that our national Constitution evolved out of such as property owners being able to vote. I don't see that it was "deeply flawed " since it was amended as needed. It's around 1902 when the people brought Jim Crow laws into the state. But Woodrow Wilson also brought Jim Crow to Washington D.C. and segregated bathrooms in the WH etc.
The original one had the Virginia Declaration of Rights. Later expanded to include more from the national BoRs such as due process.
