The damage has been done to Samsung's sickly 990 Pro SSDs despite the new firmware fix

pcgamer.com:

Samsung has rapidly released a firmware update for its troubled 990 Pro premium PCIe 4.0 SSD. The news comes just a week after Samsung promised to do just that(opens in new tab).

If that seems reasonably timely, problems with more than one Samsung drive have proliferated into something of a palaver in recent weeks. As we reported previously, some Samsung 990 Pro(opens in new tab) drives seem to be suffering from rapid drive health degradation as reported by Samsung's own Magician SSD tool.

Initially, owners reported that Samsung was refusing to process returns, but as reports of the problem multiplied Samsung began to recognise the issue was real and began replacing drives. We also note from reports from Redditors(opens in new tab) here that it's probably a good idea to shut down your PC during the update process, especially if your 990 Pro is a boot drive.

The drive itself will not reboot unless fully powered down, which a mere reboot of the PC won't achieve, and thus will be left unresponsive if the new firmware, version 1B2QJXD7, is applied without a full power down, leading to ye olde blue screens and PCs falling over.

There is also the issue that, while the firmware fix might put a stop to the aforementioned drive degradation, it doesn't reverse it. That means if your drive has been suffering the damage has already been done.

Of course, the 990 Pro isn't the only Samsung SSD to have issues of late. Reports of the older 980 Pro being subject to unexpected mortality(opens in new tab) due to a freak firmware issue, forcing Samsung to roll out a new firmware for that drive.
