You'll have to do as nc50lc suggests.

If that doesn't work and there's another file corruption, you'll be better off reindexing to a new folder if you have enough space an dpotentiallu move your current data dir off the drive (you can keep the main parent and just move the blocks and chainstate if you do that).

Now a different file in the chainstate folder is corrupted.

You can delete that particular file and restart but...
Check your HDD for hardware issues like bad sectors first so you wont lose more time on deleting corrupted files and trying over and over.
You can use HDDScan, Hard Disk Sentinel or other disk check-up tool online (most of them work with SSD too).

Hard Disk Sentinel's output:

The status of the solid state disk is PERFECT. Problematic or weak sectors were not found.
The TRIM feature of the SSD is supported and enabled for optimal performance.
The health is determined by SSD specific S.M.A.R.T. attribute(s):  #202 Percentage Of The Rated Lifetime Used

No actions needed.

Most common reason are faulty RAM, failing HDD/SDD or broken SATA cable.

Download crystaldiskinfo and see if there are any warning/caution for your HDD/SSD. If there are any warning/caution, it might be the reason.

Just a reminder to OP: Do not do anything to the data directory unless Bitcoin Core was properly shutdown.
I'll introduce more issues if you delete/rename those files while core is running.

As for the issue, the log says it all, you can follow jackg's reply delete/rename "060915.ldb" and it should work unless there's a hardware issue.
Tried it, and it happened again.

It's in your debug above, are you used to launching core from the command line?

If not you'll want to hit start+r and type cmd and hit enter...
Then find where you open bitcoin core from (start menu or desktop). Right click the icon and click properties. And copy and paste the target value into the command line. Follow it by a space and add -debug=leveldb to the end and hit enter.

What does - leveldb=debug return? Looks like it's suggesting that at the bottom to pinpoint the error.

You might want to *try* renaming the last chaindtate but I haven't seen it work before but it could be the sticker if that file is corrupted and it just wants to delete it but can't at an io level.
leveldb=debug ??
I cannot find a reference to it..

Most common reason are faulty RAM, failing HDD/SDD or broken SATA cable.

Download crystaldiskinfo and see if there are any warning/caution for your HDD/SSD. If there are any warning/caution, it might be the reason.
I don't see any problem.

Try renaming the last blk file in the blocks directory of the data dir for bitcoin core and try again.

What is the default directory for potcoin? Bitcoin and litecoin use different data dirs so it might be a hardware issue if the above doesn't resolve it.

Now it keeps crashing.

Did you same error message (Fatal LevelDB error: Corruption: block checksum mismatch) on debug.log on time when it crashed?

I'll search for "error" from top to bottom:

Try renaming the last blk file in the blocks directory of the data dir for bitcoin core and try again.

What is the default directory for potcoin? Bitcoin and litecoin use different data dirs so it might be a hardware issue if the above doesn't resolve it.

Now it keeps crashing.

What does, bitcoin core? Did you run it with reindex?

Potcoin data: C:\Users\-user-\AppData\Roaming\Potcoin

Does it make any difference that I'm running it in pruned mode?

Try renaming the last blk file in the blocks directory of the data dir for bitcoin core and try again.

What is the default directory for potcoin? Bitcoin and litecoin use different data dirs so it might be a hardware issue if the above doesn't resolve it.

Version: 0.19.0.1
OS: Windows 10 Pro

It has redownloaded the blockchain multiple times all with the same result.
Litecoin has done the same thing.
seems to have been caused by running Potcoin core and either one of Bitcoin Core or Litecoin Core at the same time.
