0.16 crashes when changing from 1D stip to 2D Matrix and clicking on save. 0.15 seams fine

[Andro-Marian]

What happened?

Crashes when changing from 1D to 2D and click on save

To Reproduce Bug

1. Fresh install the latest beta 0.16.
2. Open settings -> 2D Configuration -> Strip or panel: change to 2D Matrix -> Click: Save

The connection was reset

The connection to the server was reset while the page was loading.

### Expected Behavior

To save the settings

### Install Method

Binary from WLED.me

### What version of WLED?

0.16

### Which microcontroller/board are you seeing the problem on?

ESP32

Rebooting...

Still crashes

[blazoncek]

Crash dumps point to issues with networking stack. As with your previous report I am suspecting not WLED related.
You may also want to monitor your network traffic if there are any unusual packets broadcast.

[Andro-Marian]

I don't think is the internet. Is different. And just when saving on the 2D setting page. No problem on 0.15 release for some reason.
And again. no problem on other versions.

[blazoncek]

There were no changes to 2D set-up.

[Andro-Marian]

Crashes even in AP.

Something pointing to: serveSettings(AsyncWebServerRequest*, bool) at wled00/wled_server.cpp:669

669 is a return from

      if (request->hasArg(F("revert")) && inLocalSubnet(request->client()->remoteIP()) && Update.canRollBack()) {
        doReboot = Update.rollBack();
        if (doReboot) {
          serveMessage(request, 200, F("Reverted to previous version!"), FPSTR(s_rebooting), 133);
        } else {
          serveMessage(request, 500, F("Rollback failed!"), F("Please reboot and retry."), 254);
        }
        return; <- here for some reason
      }

When this rollback version was added. May worth testing before it.

Can't find what changed from 0.15.0.
I closed it for now.

[Andro-Marian]

0.15.1 seams to work fine on this

[Andro-Marian]

This seams to be happening if the Leds count are 30. If i bigger the crash not occurs for some reason.
Need a way to debug this but not sure how. I don't know if here is a way to download all the previous builds to try.

[Andro-Marian]

I think the: #4658 adds this bug somehow
