To avoid crashing when the file path contains non-ASCII characters, I changed the location of the * .mip files.
Now by default, they are in "profiles" next to the "cache" folder.
You can choose the location, either "profiles" or as before next to the input file to be processed in:
Preferences / Image processing / Mip profiles
If you choose "profiles", no crash problems due to NON ASCII characters, but if you have the same image file in different folders, there will be only one file "mip"
If you choose "Next input files", the system crash with path with NON ASCII, but you can have one mip file, for each same file in different folders.
Normally at start-up, the system should not crash, but it will ignore the previous settings.
I do not provide build, wait for someone to do it.
