Trouble opening app live test

I’m having some trouble trying to open my app’s live test on my phone, i had already done it (open it) on my device and it had gone well, but now out of nowhere it doesn’t let me open it again, once i click on my project it gives me the usual warning about the ble device but after that it says that there’s some issues with my blocks and i haven’t changed anything before, it had already worked. I already tried changing and deleting some blocks thta i thought might have been the problem but it’s still the same. Does anyone know what i can do to resolve this problem?

Your project might be cached in your browser and compiling using something other than the blocks you are seeing. This happens somewhat frequently with Thunkable. Try refreshing your browser tab (save/duplicate the project if needed as a backup). Force quit the Thunkable app on your phone. Then try to Live Test the project again in the refreshed tab.
