Hello! Lau12345
Thank you for posting in Microsoft Community
As per checking the information shared that you are having trouble connecting to SQL server with the use of Microsoft Access on Insider preview version. Based on the description it seems to me that your concern is out of my field of expertise as I can only do basic troubleshooting steps for Microsoft Office programs, OneDrive, and Outlook.
We will leave the thread open in case some Volunteer Moderatos or other community want to join in.
You may also share your concern here in: Questions - Microsoft Q&A
Thank you,
