java.io.IOException: Cannot run program "___REMOVE___/esptool.exe": CreateProcess error=2

After compilation of a sketch (which takes a picture with the ESP32-CAM and saves that on SD card and then uploads it with FTP) there are no errors.
However when I upload also the skecth after compilation to the ESP32-CAM board then there is a failure, because esptool.exe is not found:

Error during loading of the sketch

What may be causing this failure?
Maybe esptool.exe is not found? Otherwise how to install it and in which directory?

Thank you for your help

Thank you for your reply.
Yes, exactly. That has solved the issue! Locally I had received a message with a link that describes the problem and the solution.
The link is https://github.com/espressif/arduino-esp32/issues/7923
Now this is what the Serial Monitor (IDE) shows:
09:59:41.573 ->
09:59:42.461 -> ..
09:59:42.977 -> WiFi connected
09:59:42.977 -> Camera Ready! Use 'http://xxx.xxx.x.x' to connect.
I opened the URL in my browser and got directly the page (ESP32 OV2460) with the red GET STILL button. After clicking on that button directly also the camera picture.
However it often happens that although the WIFI signal is strong enough that the page is not always loaded, ending in a time out.
I had tried an other WIFI network. Same problem. So the ESP32 cam (I am using a AI thinker ESP32-CAM) is not responding.
But that issue is maybe for another (new) thread.

This thread may be closed.
