"The directory name is invalid" error popup

Hi, you need to know its origin. There's little to go on from the message itself.

First, is it a Windows message, or from some program?

Try e.g. Winspy
WinSpy - Window Information Tool - AutoHotkey Community

and drag the finder over that dialogue box to identify the underlying process and see if that tells you anything useful.

Second, you can try a process of elimination. Perform a clean boot (Google or see tutorial if unusure how).
Do these still occur?

If not, you can try enabling startups to see if you can identify the originating program.

Third, as a matter of good practice, and wise periodically anyway, run some disk checks just in case.
Hard Disk Sentinel (SSDs too) is excellent.
Examine the report on its GUI for each disk of concern.

If all is ok, then run
chkdsk X: /scan
from an admin command prompt
for each disk or partition of concern changing X as appropriate.

Just some clarification

The drives that mention in this popup are from my SD card reader
which is currently empty (does not have any SD card etc) mounted

For some unknown reason explorer is trying to open these empty drives

Winspy reports it is coming from explorer

Code:

D:\
ahk_class #32770
ahk_exe explorer.exe

I unplugged the SD carder reader and haven't seen the error popup so far..

If I plug back my SD carder reader, the error will likely occur again

So not sure how to fix this issue...

Sounds like it could be dodgy- presumably it's an external USB device.. basics- consider port, cable...
