Bitcoin-qt 25.0.0 with complete up-to-date blockchain as been running fine for a while now on a Linux Fedora PC.
I closed the wallet and created another one, just to contain some funds from a paper wallet.
After "importprivkey" the wallet started to rescan the whole blockchain, which took quite a long time.
In the morning a "Rescan failed" error was on the screen.
Although, the funds where available. After a second attempt, same error.
Then, I closed that new wallet and re-openned the original wallet. Repeated the "rescanblockchain" and the same error popped-up again.

It appear the error is not dependent on the wallet, since both wallets do the same thing.
Error message: https://ibb.co/5KChMNP

I search this forum for potential solutions but none came out.

The Questions:
1- Is there something I can do to remedy the situation other than download the whole blockchain again ?
2- Could that error have an impact on further transactions ?

I'd like to avoid having to download the whole Blockchain again, that will take a long time.
