I can’t see any info about the wallet in the Blockhain.com Explorer either.
Do you have the wallet address? Blockchain explorers only recognize details linked to the blockchain like public addresses or transaction ids, a wallet identifier for a particular service would not be recognized.
Is this wallet locked somehow?
You would need to contact their support service for assistance. I believe blockchain.info changed to blockchain.com some years back, so you'll need to verify you're on the active site before making your inquiry.
I should add that you do not need to reveal sensitive details about your account online, except it is absolutely necessary and does not risk your funds or privacy.
