No valid files were found in the source directory provided (part 2)

[KaraokeAmerica]

🦟 Describe the bug
It is identical to bug 91 that was closed with no updates:

When you try to Merge subtitles, it says "No valid files were found in the source directory provided."

Steps to Reproduce

Set source directory to "any directory I tried"
Set output directory to "Match Output"

Expected behavior
The first time installed and used this program it worked perfectly. I have found something awesome!

Two days later I tried it on the same PC and this happens. I have done a repair install, then uninstalled it, deleted APPDATA folder and reinstalled. Same issue. I even manually converted one of the MP4 files in that folder to MKV using MKVToolNix and get the same error.

the error.log file is empty even after this fails. It is 0 bytes in size.

I have rebooted my system multiple times since I opened this thread. Not until the last time did it work again, but just once. I immediately tried a second folder and it failed again with the same error.

I enabled debug mode and tried it again. It still failed of course but I also got this:

Don't know if that is useful.

This morning I tried it out of the blue doing nothing different, no reboots etc and it worked......once.....:(

Same here.

Just had this happen to me for the first time today as well. Nothing has changed that I can think of.

Same issue here, any hope this is still being worked on or is this abandoned?
