Bitcoin Core makes heavy use of CPU, RAM and disk IO. Hardware defects might only become visible when running Bitcoin Core. You might want to check your hardware for defects.

* memtest86 to check your RAM
* to check the CPU behaviour under load, use linpack or Prime95
* to test your storage device use smartctl or CrystalDiskInfo

ram and cpu are fine, and i believe the drive also is working fine. i took the files and moved them to another HDD. still same issue on launch.

Could rebase, as CI on master should now be passing with clang-15 in.

Yes, file corruption can not be fixed by moving the corrupt files from one storage to another.

What package manager exactly?

Does the error happen with the recent official Windows binary from https://bitcoincore.org/bin/bitcoin-core-27.0/ ?

Direct download from https://bitcoin.org/en/download.
I hope its called a package manager, or its my mistake for filing it as such.

I think a `-reindex-chainstate` should be good enough.

While testing this PR I faced the problem that running linters [locally](https://github.com/bitcoin/bitcoin/tree/master/test/lint#running-locally) alters the ownership of some files in `src` to the `root` user. How to avoid such behaviour?

Is this an external HDD? What is the filesystem?

I didn't add the docker image, nor is it modified in this pull request. If you have questions about docker or the linter usage, a separate issue may be more appropriate.
