Recover corrupted Zcash wallet.dat?

[Andartis]

Hello,

due to a really stupid chain of events, I ended up with a corrupted wallet.dat file of a Zcash wallet after a worst case scenario with data loss. Please do not ask about the seed phrases, I know they should have been backed up and with this exception my seed phrases are very safe for every other wallet - except this.

Now, I am trying to dump the wallet.dat for the private keys with pywallet. But when trying to dump the wallet with

Code:

python pywallet.py --dumpwallet --wallet=C:\*pathtowallet*\wallet.dat > wallet.txt

into a txt, I am getting

Code:

(22, 'Invalid argument -- BDB2509 the log files from a database environment')

Maybe there is another way to do this?

Thank you in advance!
