Preview program error

Hello,
sometimes it happens that I modify the source but launching the game, in the preview window the code modification does not change anything. it seems to have a kind of cache that is not emptied by the previous test. this is very inconvenient because I’m not sure if the problem is in my code or in the preview. the solution is to restart gdevelop. it happens to me on Windows from various versions.
Is there any solution to avoid it?
Thank you

This never happens to me…

Hi this is what I do, delete all keys but don’t delete gd-preferences key

Thanks,
I’ll try soon
