Notebook Operating System and Recovery

Had corrupted files and did a factory reset, i put all my needed files on an external drive prior. Reset was done correctly, start up good. Took first notice that the date and time were wrong fixed that. I only have Edge and Chrome as browsers and they both throw at me Your Connection Is not Private error messgae [err_cert_authority_invalid], clicking advanced to proceed to sites does nothing just more of the same errors.

I have searched every nook and cranny about fixing this error and nothing works, as its not a browser issue but a computer and there's something not communicating within my laptop.

I only have Windows Defender as security right now because i can't go to any web page to download what i usually have.

This is where you come in. Please help, my laptop is used for work and i can't get into the website. I am pretty tech savvy but this always confuses me and is a simple fix but i just can't wrap my brain around it.
