... and the failure of all types of file systems is also a known bug?

That little `qio` is quite relevant!
Simply adding that statement to otherwise your config makes now my complete pio.ini:
and now all three file systems FFat, SPIFFS, and LittleFS do work! And also NVS is working! All can be created, mounted, read from, written to as one would expect.
However:
My motivation to test the S2 comes from the fact that the ESP32-"classic" has a major, major problem when downloading files >150k! Files of around 300k present the biggest problem! In easily up to 50% of any download attempt the Watch-Dog-Timer triggers (on 'async_tcp'), resulting in aborting.
The severity seems to depend on the device and the flash used (i.e. flash manufacturer dependent). I had concluded that the ESP32-"classic" has either a hardware defect, or a software defect, or both, but certainly isn't fit for commercial use when big files are involved.
Unfortunately, in this aspect the ESP32-S2, with the present code, is even worse! Here the failures are at 95% if not higher!
Opening the Network tab on any browser's toolbox shows that from a 300k file only 100k ... 150k are downloaded, then the ESP crashes, and eventually the browser times out.

A bit strange:
My previous post shows that I get the S2 chip to work properly with any File system and NVS by defining 'board_build.flash_mode = qio'.
But running one of the IDF example scripts on the very same device gives me:
So, IDF thinks 'DIO' is correct, and not 'qio'.
When I attempt to force 'qio' by inserting into platformio.ini the line 'board_build.flash_mode = qio' it compiles and executes ok. However, my forcing seems to be ignored, as the debug output is the very same as above, namely 'DIO'!
If we trust the IDF output as correct, then it would mean that the Arduino framework has got this flash stuff in reverse to what it really is?

I struggle with similar issues as you and played with DIO/QIO as well.
When you define in platformio.ini flash_mode as QIO it compiles and works (at least somehow), if I compile with DIO then my LittleFS or SPIFFS can't be mounted.
So, I compile with QIO (until a stable framework release).
On the other hand, my flash doesn't support QIO mode (quad IO). And VS Code automatically flashes with DIO parameter.
Just for fun, I tried to flash manually with QIO param and, surprise surprise, it doesn't work.

In a recent days a new version of PlatformIO/Espressif32 was released:
They fixed QIO/DIO bug. So I compiled again with DIO and I'm back to the previous step

Well, now nothing works 
I also upgraded platform espressif32 to 3.3.1 and my code from above posting.php?mode=quote&f=19&t=22209&p=80731#pr80731 no longer works. All I get in the monitor is some - I believe - bootloader code, which repeats endlessly.
Removing line `board_build.flash_mode = qio` from pio.ini and it compiles fine and runs. WiFi works, webserver works, but neither file system LittleFS nor NVS work!
Now I inserted line `board_build.flash_mode = dio` into pio.ini to set it explicitly. The result is the very same as if not inserting it at all.
So, you can't go with "qio" and you can't go without it!

I'm trying now to compile with the latest Arduino engineering release RC1
But compilations fails with this error
Trying to solve this issue, who knows, maybe this release is better than 'alpha1'.
