Failed to load map!

Hi, I have a problem, I can no longer load my project. When I launched the project, I had to choose the engine version (5.3 or lower). My project is in 5.4.3, but it has been downgraded to 5.3 and since then I have had the message ‘Failed to load map! What should I do? Thanks for your help.

If I’m assuming correctly your map must be in your explorer but not loading up. Best case scenario try to run it in 5.3, if it works well and fine just make a copy of it and reinstall 5.4.4 and try to open one of the copies.

Worst case scenario I think your map itself got corrupted.

Thank you for your help. I’ve uploaded a backup from 4 days ago and it’s OK.
