I have never used Alicebob wallet and I don't know how it works.
Can you see list of your addresses on Alicebob wallet? If so, check if they are same as addresses generated by electrum.
Husna QA tested with both Alicebob wallet and Electrum wallet. Same addresses in both wallets.
I got the address from the AliceBob wallet, which was imported into Electrum; both display the same address.


The problem with OP is whether he has the wallet private key/ mnemonic seed. If he has it, he can import it to Electrum and it's done like Husna QA tested successfully. If OP does not have private key/ mnemonic seed, it's done in another way, he lost that wallet and bitcoin.
No private key, no access to your bitcoin. Import a public address will create a watch-only wallet, and with it it's unable to spend bitcoin.
