Vuylstekeara in S/H need to be reassured
The roots were alive when you bought it. It is normal for the roots to die when they go into S/H. The plant needs to grow new roots that are adapted to S/H.
It is better to move plants to S/H when they are beginning new root growth so the new roots can grow into the LECA and become adapted. If you move a plant when it is not making new root growth, the old roots may die before new roots form. This stresses the plant and pseudobulbs wrinkle, which is happening to your plant. You can remember this next time and not move a plant to S/H until it is making new roots.
Your plant will not recover until it grows new roots. Normally intergeneric Ondicium hybrids like this can grow well in S/H, but it may take yours a while to recover.
Putting it in bark now will not make any difference. I would leave it in S/H.
