Installing Reshade" infinite load | no effects in subfolders detected

I fixed the issue(s), but maybe something can be done, so it won't happen for anyone in the future.

The steps to more or less reproduce the issue(s) are the following:

I have game Airborne Troops.
d3d9.dll renamed to dxgi and installed dgvoodoo.
Almost all shaders installed.
Created some presets.
Performed multiple actions of ALT+F4 and reopening the game
I opened dgvoodoo control panel in backrgound
Performed multiple actions of ALT+F4 and reopening the game

What happened?
Looks like Reshade.ini have been reset - no shaders are detected and providing manual paths doesn't detect all shaders - specifically those which are in subfolders (shaders\xxx\)
Uninstalling Reshade showed error on exit with log file write protected.

Installing Reshade is impossible - it hangs on installing Reshade (before picking shaders)
Bug cause - dgVoodoo Control Panel - after closing, logs can be deleted and Reshade installed again
(injector was deleted, I think everything beside logs was deleted)

Summary:

Reshade.Ini was reset probably after one of ALT+F4 actions
(why it was reset?)

Why shaders in subfolders couldn't be detected after ini reset?
>Because every shader folder needs to be added separately
(would be nice to somehow detect shaders in subfolders)

Fix:
Closed dgVoodoo Control Panel and reinstalled Reshade (shaders to download detected and added to ini automatically after choosing preset),

After 8 hours I triggered the same issue of Reshade.ini reset after few of ALT+F4 and game reopening actions.
Ini is completely empty.

Don't know how it was in previous case, but now it was most probably due to 0B (0 bytes) of free hard disk space somehow.
