When posting tracebacks, *copy* and paste the full traceback *with hard
returns* so lines are not joined together as above. With them inserted,
the above is:
File "C:\Python38\lib\os.py", line 818, in fsdecode
filename = fspath(filename) # Does type-checking of `filename`.
TypeError: expected str, bytes or os.PathLike object, not list
fsdecode is being passed a list as a filename. Look at the full
traceback to see if that comes from you or something internal.
Any advice on how to fix version 3.8 would be appreciated.
Don't assume that 3.8 is the problem and in need of a fix. Maybe your
code depends on a bug in 3.6 fixed in the 3.8 you installed. fsdecode
itself is the same in 3.6 and 3.8. On Windows, fspath is supplied by
the C-coded nt module. You could search the change logs in What's New
3.7 and 3.8 for mention of fspath.
