While what 'Draconifors' said may be true, I would still recommend you contact SUPPORT either:

'
10. VIRTUAL CURRENCY AND GOODS'
It states, in part, the following:
'10.2 Payments. As GOG is the entity which provides you with the access to Gwent, any content purchased in an in-game store will be purchased from GOG and may be subject to legal documents presented to you by GOG. If you buy Virtual Goods and/or Virtual Currency from GOG, you agree to the pricing, payment and billing policies applicable to them, as notified to you at the time of purchase. All prices are visible in the in-game store. They’re inclusive of legally applicable sales taxes/VAT. You can pay in different ways: (i) using a valid debit or credit card; or (ii) using PayPal or any other authorised payment providers; or sometimes (iii) with GOG Wallet. The GOG Wallet is made available subject to rules which are set out on our GOG Wallet page here. We support multiple local currencies (see our Support section here for details). However, if your local currency is not supported, you can make purchases in US Dollars. Please be aware that in such case you might have to pay a currency conversion charge or other transaction fees set by your bank. You are responsible for ensuring that you have authorization to use any chosen payment method, which includes obtaining account-holder/parent/guardian approval if applicable. You are responsible for ensuring that this authorization is maintained at all material times. Keep your payment details secure. Do not make inappropriate charge-back or refund requests. You are responsible for applicable fees and taxes. All payments are non-refundable and non-transferable except as expressly provided in this Agreement.'
According to this, it is GOG that are responsible for all purchases since the purchases are made through their store. I guess, although am not certain, this means you need to contact them about the issue and *not* CDPR. Perhaps it would be advisable to contact both.
Also, there are different legal right depending on whether or not you live in a European Union country, or outside of it.
Regardless of the legal issues and terms and conditions, one would hope that the companies involved would take a common sense, reasonable approach to such an issue - again based on
GOODWILL.
It would probably work to your advantage not to seek financial reimbursement, but make clear that you would be happy with even a portion (three quarters, a half, etc.) of the meteorite powder being added to your current GWENT account for use in the game as it exists today - it's unlikely they'll give, or want to give, everything (if anything).
Remain polite and reasonable when corresponding. Reinforce the position that such a
GOODWILL gesture will guarantee your long-term support for the game and that future purchases would be certain (these past purchases are proof that you are prepared to spend a lot of money on GWENT - a lot more than I ever have - I break into a sweat paying €5.00).
Ultimately, if the company declines your request then don't immediately give up. Restate that failure to provide a solution will result in you ceasing to support GWENT, GOG and CDPR now and in the future. Based on your purchase history, I'd have to believe these companies fools to not provide you with something as it's clearly likely you'd be prepared to spend lots of money in the future.
Finally, there is this section:
'
18. DISPUTE RESOLUTION AND BINDING ARBITRATION'
'18.2 Informal dispute resolution:
We and you both agree to make reasonable and good faith efforts to resolve any dispute between us informally. Normally we would suggest that this dispute resolution period lasts 30 days unless exceptional circumstances exist. If it is not resolved during this time, the next steps depend on where you live...'
I suspect you live outside the EU, and probably in the USA (having paid in dollars).
The 2nd section may be more applicable: '(2) Dispute resolution next steps: if you live in the USA...'.
I'd hope it doesn't come to that point, and either GOG or CDPR demonstrate an amount of reasonableness by means of a
GOODWILL gesture. If they don't, shame on them and they deserve whatever they get as companies (i.e. to fail miserably).
Check out your local consumer rights and applicable laws.
I wish you well.
