Running on 2. computer EXEC file?

Hello, I have the following problem:

I use Cryptomator and created a vault that is stored on web space. I have mounted the web space in Finder on both my iMac and my MacBook, so it can be accessed directly through the system.

When I open the vault with Cryptomator on my iMac, a folder appears, and that folder contains three Numbers files, exactly as it should. However, when I open the vault with Cryptomator on my MacBook, the vault opens, but instead of the folder, an EXEC file appears.

How can I fix this problem?
