I don't know if it will help but a lot of computer shops with service departments can perform repairs on video cards. The problem of course is that you might end up paying more for the repair than if you just bought another video card.
I don't know what kind of financial shape you're in but I did get a working RX 580 2048SP 8GB from AliExpress for only $70CAD including shipping. That's only like ~$52USD. It's some weird brand called JXZ Jisoonzer (I'm serious, that's what it's called...LOL).
I bought it for my mother's HTPC because she's using my old FX-8350 but it wouldn't work with her BIOS because, for some odd reason, it only likes UEFI, something that her 990FX motherboard (that I bought in 2011) doesn't have. I ended up getting lucky and found some weird clearance sale on a Powercolor RX 6500 XT ITX. It cost me about $180CAD:
The card's performance is pretty trash for an RX 6000 as it's only 13% faster than the RX 580 2048SP (and that's only if you have PCIe4). I was actually worried that there would be problems because a 990FX motherboard only has PCIe2 and so this card would be running at PCIe2x4. It works just fine for 2D applications though and has a TDP of only 107W instead of 150W so, good enough.
I didn't know about this strange aspect of Polaris cards and I took it to a Memory Express store to be tested. They said that the card was defective and gave me a printed estimate to that effect. I submitted that as evidence that the card was defective and successfully got a refund from AliExpress. About a month later, I was tinkering with the card (took the cooler off, put new thermal paste on the die, etc.) and, to my shock and amazement, it worked perfectly on the Biostar A320MH motherboard that I used for tinkering.
I found out from a user named eidairaman on TPU that it wasn't uncommon for Polaris cards to require UEFI to work properly. I felt pretty bad about getting the refund because it was a great deal to begin with but, by that time, it was too late for me to do anything about it. The card works though, I tested it with 3DMark, Unigine Superposition and did some benchmark test runs with older games like Godfall and Far Cry 5. It played those games just fine at 1080p native and for more advanced games, it supports FSR.
I know it's not ideal but it could be a workable option for you.
