TagSpaces showing "Searching..." and not applying Filter

Hello,
Two computers pointing to the same local folder on a shared drive. On one TagSpaces works as expected. On the other, when entering a search into the search bar it shows and stays on “Searching …” at the bottom of the screen but does not apply the filter. The settings on both computers are the same. Any suggestions what causes this and how to solve it?
Searching Error

Strange behavior! Which version of TagSpaces are you using and which operating system?
