"Leading DApps hub on Polkadot that supports Ethereum, ZK Rollups and Optimistic Rollups" - the official description of Astar Network, and the keyword here is "DApps hub". Since DApps = DeFi and Liquidity nowadays Astar has failed to become the leading hub on Polkadot within one year of its launch. The reason is that Polkadot itself could potentially fail to capture a significant share of the market compared to other blockchains.
Anyway, there is a severe lack of liquidity in the Astar ecosystem, especially after the May 22 crash, resulting in a dearth of meaningful on-chain activity for now.
Also, they should resolve the fragmented liquidity problem. Since assets are only available on one blockchain at a given time, liquidity in the application becomes fragmented across multiple on-chain environments. Consequently, there is less liquidity within each deployment, leading to higher slippage and reduced trading fees.
