Fix Windows 11 Crypto payment process Crash

Job ID: 40060148

Budget: €3,000 – €5,000 EUR

My Windows 11 desktop app includes a cryptocurrency-payment module, and that module keeps crashing the moment a user tries to pay. The crash happens every time, so no transaction ever reaches the network. The payment layer is part of a custom integration (it isn’t a browser flow or web checkout) and runs natively inside the app.

I need someone who can:
• Analyse the crash logs, reproduce the fault, and isolate the root cause
• Patch or refactor the code so the payment process completes without exceptions
• Verify that the repaired build handles successive transactions safely on Windows 11

Please be comfortable working with wallet APIs, desktop-application debugging tools, and the usual blockchain libraries so we can move quickly from diagnosis to a stable release.
