Ok so I closed the Arduino IDE thinking that it was done uploading...guess not. Now every time I try to upload a sketch even a blank one it shows the error avrdude: ser_open(): can't open device "\.\COM6": Access is denied. I have tried selecting a different port number in windows device manager, and ensuring it was selected in the ide. Is there any way to fix this if the IDE was closed before the upload was completed?
what Arduino board are you using?
pro micro, and this issue is present on 2 of my nano every's
On the Pro Micro this is usually a bootloader issue. See fix here:

The Nano Every does not have a bootloader so the error cannot be the same.
I just verified and it is the same for the everyies
honestly I think it is an issue with the IDE despite it having the correct com port selected and this was on an Nano Every that I havent tried uploading the sketch to. This is the sketch privided by Real Robot that has the modular joysticks.
when I have an issue with PORT on my PC (I have Arduino UNO, Nano, 33IOT and 33 BLE but no Nano every), I double click the reset button, till the power led is flashing.
It puts the card in boot mode and usually solve any issue (if the board is connected in a normal way to COM6, it shifts to other PORT when double click).
I will try that on the everys but When I use the older Arduino IDE it says the com port is busy. I may just uninstall both ide's and reinstall just one. With this issue being present for a board that hasnt been touched it just doesnt make sense.
right!
a fresh install of the IDE could be a good idea. If you can, use a USB adaptater (any "multi inputs"), another USB port, and eventually another PC.
No issue with the USB port itself? (providing charging current for a phone or other, reading an USB storage data...) ?
sooo this is what came up on my laptop "different pc"
"Connecting to programmer: .
Found programmer: Id = "CATERIN"; type = S
Software Version = 1.0; No Hardware Version given.
Programmer supports auto addr increment.
Programmer supports buffered memory access with buffersize=128 bytes.
Programmer supports the following devices:
Device code: 0x44
"
that was the pro micro
for the Nano Every's it said it couldnt find "flash" and "boot" memories in the description.
for both cases I just tried uploading a blank sketch
This is normal for the Nano Every.
I am a little lost by what you mean by normal.
That message is present when there is a successful download of code over usb with avrdude from the ide on the pc to the Every.
Ahhh ok. well atleast these boards are not bricked.....now for the pro micro issue.... thanks for clearing that up.
What I thought was a pro micro is a leonardo with a usb transceiver. Amazon.com I guess having the incorrect board selected was causing issues with it being busy.
of course now "Joystick.h" isnt found.....and it is a 32u4 based board
