When I attempt to "Open Wallet" in Core v26.0, and this also happened in v25.0, it hangs. Nothing is written to the log file, the menu stays open and then after a couple minutes closes as if nothing happened. I've rebooted, reinstalled core, etc.
Any thoughts?
One of the reasons for this might be corrupted database. Did you initiate IBD process after reinstalling Bitcoin Core? The reason I'm asking is that sometimes reindex and/or reindex-chainstate don't help to correct the faulty copy of blockchain on your machine thus starting download from scratch saves both time and nerves.
