Whilst tidying up my testnet wallet addresses, I have come across a crash whilst running importprivkey.

Client Versions:
v4.0.1.3-g2437d57fc (Integrated Scraper)
v4.0.1.3-g015a41b0b

OS/Arch:
Win10 x64
Debian x64
Debian Arm64

Description:
Client goes "not responding" when running an importprivkey command from the GUI console at least 50% of the time. If you crash out of the client and restart, you find that the command has completed successfully however.
