Maybe also try a minimal sketch, e.g. no wifi, just a loop with delay and Serial.print statement to check basic operation of module.

I will try this tomorrow.
By the way, is there any possibility (program?) to determine if the ram or something else is corrupted for a defined ESP?
Something lile the checkdisk of windows...

I use the Arduino environment and the default (in preferences) it to verify on upload. If it didn't get programmed correctly I would expect a failure notification at that time.
I looked at Expressif's ESPFlashDownloadTool_v3.6.2 and I didn't see anything there, no separate button for verifying. It is normal to automatically verify after programming. I didn't try loading with that tool so I don't know if any additional options are present after programming.

I try with other module and it works...
So the current module is definitively broken but once again i did not understand why the module works at higher supply voltage...
