I encountered this problem yesterday. First of all, I went online to inquire about these three solutions

1: Use the command fluent clean (some users report errors and solve them)

2 manually delete all files in the build/APP/APK and build/APP/outputs directories

3. There is also the official command to use fluent create

These three solutions failed to solve my error reporting. Then I suddenly had an idea that my outermost folder was a Chinese name. Sure enough, I solved the error reporting after I changed the Chinese name to the English name. I hope all developers will not encounter such a bug
