Any ideas on disassembling the microSD card without damaging the board or controller pieces?
In 99.999% of all micro SD cards, it's a monolith. There's nothing to "disassemble" it's a single microchip.
Windows asking you to repair that SD card was the warning sign you ignored. It probably started as bad sectors, then got worse as the NAND degraded.
You can try heating and/or cooling it. Occasionally that'll get it working for a minute. But, it's not likely to work.
Aside from that, you'll need professional recovery and can expect to pay between $1,200-2,500 for it. It's very tedious to have to sand down layers of a chip and microsolder into the tiny traces. And, half the time it turns out to have been all a waste of time anyway. I personally hate these cases.
