Firstly I am assuming the responsibility for this loss, it was my mistake and if I cannot get back my coins, that is something I will have to deal with myself. I won't blame anyone other than me.
Back in 2018 I purchased some Monero and stored it in my Windows GUI Wallet (v0.11.1.0) using a local node and kept it in a spare computer I that I only use for crypto.
A few days ago (precisely on the 16th of may 2021) I logged in my Windows GUI Wallet (v0.11.1.0) and performed a transaction moving all my funds to a new address. The transaction did not finish successfully as I couldn't find it in any Monero blockchain explorers.
I did some research online and I found someone who had a similar issue. I followed all the steps on this link here:
I noticed that the transaction status has changed to Failed, but the funds have never returned and my balance is still zero.
I tried different approaches to solve this issue, with different Wallet Versions. In the first attempt I performed a database conversion that took more than 24 hours to finish. Then I tried remote nodes and also accessing the wallet by the CLI, but nothing worked.
This is what I see using the CLI:
[wallet 48doH9]: balance Currently selected account:  Primary account Tag: (No tag assigned) Balance: 0.000000000000, unlocked balance: 0.000000000000 [wallet 48doH9]: rescan_spent [wallet 48doH9]: show_transfers failed out - 2021-05-16 21:35:53 3.168872840000 8bab9614f5aa07f69481c5d01dff3fc111d01c3f1a33f5eb8e788041bafc8eff 0000000000000000 0.006060080000 48fGK9GYBrPSTMt23FUYMuZXuv7K37GrCi4ss7Um8RopVU4yPDt8CppPvkvyCDDapCQApnqPHyY1P3PcayBuq7wvEhoFYJL:3.168872840000 - [wallet 48doH9]: balance Currently selected account:  Primary account Tag: (No tag assigned) Balance: 0.000000000000, unlocked balance: 0.000000000000
Is there any hope or is it too late?
