videocard issue, Premiere Pro doesn't laptop's graphics GeForce 940MX

Actually, the lack of an error message for the GeForce 940MX is a good thing. It just means that the driver that was installed for that GPU is valid. If it didn't, then it would have displayed an error message for that GPU - "Unsupported Video Driver" or "Missing Video Driver."

The Intel driver, however, is a different story. Most big-name laptop manufacturers do not use generic Intel drivers at all - but an OEM-specific customized version of that driver. And unfortunately, the last Intel driver that was verified to work with your laptop dates way back to May of 2018 - version 23.20.16.4973. That's too old to be even supported in Premiere Pro 2019, let alone Premiere Pro 2020. You cannot just upgrade that driver with one that's from the Intel site (without temporarily disconnecting from the Internet, completely uninstalling all traces of the OEM-specific Intel driver, and then performing a clean install of the new driver - all before reconnecting to the Internet): That installation will fail with the error message "The driver version has not been verified by your computer manufacturer."

The only thing you can do (if possible) is to disable the intel in the bios.
