What I stated in the link in the second response applies here. Adobe is now restricting software version availability to the two most recent major versions, and that Nvidia has now completely ended all support outside of archived drivers of all Kepler mobile GPUs. And moving forward, Adobe is now requiring a driver version that's no more than two major versions old at the time of the release of a major version of Premiere Pro. Unfortunately, the major mainline driver version that was the last one which supported Kepler mobile GPUs falls outside the support window that Adobe now requires: 425.31, which was the last driver version that supported the 920M, is actually a security-patched variant of the 418-series driver version. However, in between the EOL announcement date and the release of Premiere Pro 2020, Nvidia had introduced three major versions of its mainline GeForce drivers, none of which support any Kepler mobile GPUs at all. Thus, Adobe now requires a driver version higher than 430, which was released after April 2019 (the version number is critical), just to be supported.
As for that second response itself, I did respond to that post. That system's GPU driver is simply way too old. In fact, it dated all the way back to 1 September 2017 - more than 2.5 years old (and to top it off, still included support for the now-obsolete Fermi GPU architecture in that old driver version)! Even Premiere Pro 2019 now requires a driver version higher than 396 (released after April 2018) just to be supported. And unfortunately, big-name laptop OEMs have gotten either lazy or indifferent: These companies use customized, vendor-specific drivers that cannot be easily replaced with generic GPU-manufacturer drivers, and whose most recent available driver is now several years old and have never been updated since.
Oh, and one more thing:
The tech industry either does not like to or won't support anything hardware-wise that's more than two generations old. Accordingly, starting with Premiere Pro 2019 (whose 13.1.5 version is now the oldest version of Premiere Pro that's still available for download and installation), Adobe now absolutely requires (for systems equipped with discrete Nvidia GPUs) a driver from Nvidia that no longer includes support for legacy, about-to-be-EOSL'd hardware (for the 2020 version, a driver that includes support for Kepler desktop parts but not Kepler mobile parts) just to even be supported or to minimize the risk of crashes and/or corrupted renders/exports. Previous versions of Premiere Pro didn't care as long as software-only rendering was still usable, although beginning with the no-longer-available version CC 2015.3, Adobe now requires the use of a driver that no longer included support for the Tesla architecture (first-generation CUDA, GeForce 8, 9, 100, 200 and 300 series along with a few low-end variants of GeForce 400) just to enable MPE GPU acceleration.
In other words, Adobe these days is now letting the PC hardware industry control them. This is in contrast to the old days in which their software practically ran on almost anything within a certain age regardless of the manufacturers' support status.
