Dear Jørgen Fidjeland,
Good day! Thank you for posting in Microsoft Community.
From your description, Access keeps crashing when opening 2 databases. We appreciate you share with us the troubleshooting ways that you have tried.
It seem like we cannot reproduce the issue when testing from our side. Could you share with us the version of your Access application? We will check in same version and see if we can reproduce the same situation.
Please go to File > Account, from right side of the page, capture a full screenshot of Product Information.
Thanks for your cooperation! Hope you keep safe and healthy always.
Sincerely,
Tina | Microsoft Community Moderator
