It's a tough one. This is not personal advice, but you could discuss with your tax advisor the concept of "involuntary conversion" gain deferral under Section 1033 to see if they think it applies. It's a rule that let's folks defer gains when their property is taken from them and replaced with compensation, under very specific facts/circumstances (plus they replace the old property with the proceeds). One possible crypto application is, if an exchange account was hacked and the exchange gave a person fiat as an insurance payout, that's possibly an involuntary conversion as the person didn't intend to cash out absent the theft. But your situation is less clear, as you could have transferred to another wallet, and didn't have anything stolen at the end of the day (rather you sold your asset). I would need to do a deep dive of Section 1033 regulations and cases to get comfortable with my hypothetical example qualifying (the exchange compensating an actual theft with fiat), however your example is even more ambiguous. But again you should see what your advisor thinks and if they have any other alternatives.
Thanks!
