Placa de Vídeo - MX 350 nvidia - Premiere Pro

Here's why:

Your system's actual usable memory is far less than 8 GB - in fact, closer to only 3.5 GB (as confirmed by the Windows Task Manager) after all of the default background processes are up and running. Not the 7.77 GB that Windows System Info claims (which only counts the total maximum available RAM before any required background processes are factored in).

As for the RAM expansion, as configured your laptop came with only a single 4 GB SO-DIMM, running in single-channel mode (plus the 4 GB of DDR4 RAM that's permanently soldered onto the laptop's motherboard). It has two DIMM slots, but accessing those slots typically require major disassembly. And Acer officially supports the use of SO-DIMMs no larger than 8 GB, which means that 20 GB total RAM is the most that Acer officially supports. And even then, with any memory upgrade that you make your laptop will at best run in a funky hybrid memory controller mode in which anything above 8 GB will run only in single-channel mode, which will significantly handicap your laptop's performance in CPU- and RAM-intensive apps such as Premiere Pro compared to a PC that has an equal amount of RAM but running in true dual-channel mode. Adobe recommends at least 16 GB system RAM for even FHD (1080p) video editing, let alone 4k.

Furthermore, the GPU has just the bare minimum amount of VRAM that's required to run Premiere Pro with any GPU acceleration whatsoever. Adobe strongly recommends 4 GB or more VRAM.

In other words, as configured your laptop meets Adobe's minimum requirements only in letter, not in usability.

The MX350 only has the Game Ready drivers available.

Premiere Pro works best with the Studio Drivers.
