IDE 2.3.3 Can't Find Ports

Development Tools Uploading
1

I am running Win 10 Home with 32G of memory running an i9-12900 processor. I am working on a large program (about 250K--yep, the same one for the last 5 years!) and I cannot select a port for the upload. Memory (7+M free) and stack space (147K free) are likely not the problem.

I had this problem before and someone wrote in to delete a certain file (I think it was a Temp file somewhere) which solved the problem. However, I cannot find that post and I'm old and cannot remember where the file is located or its name.

Any help would be appreciated.

Which board are you using?

PS
I don't think upload problems can be solved by deleting a file (but I might be mistaken); it it's a compile problem it's another story.

STMduino installed?

I've moved your topic so a category that is more suitable to board detection and upload problems.

@sterretje: Sorry, I forgot to add that I'm using a Teensy 4.1. STMduino is not installed.

What does Windows device manager think of your board? Is it recognised?

If you have another board like an Uno, is it properly recognised in Windows device manager and the IDE.

I'm not familiar with the board.

The IDE recognises ports through a tool called serial-discovery; not behind a PC to verify. Maybe that tool is blacklisted by antivirus software.

I found another Teensy 4.1 in my spare parts box, and tried it outside of the project. It located the port just fine. I then connected the USB connector to the Teensy I just pulled out of the project's socket. Nada...no OS "ding-dong" or ports listed.

What is puzzling to me is that the original Teensy seemed to have just "died" overnight. It was working when I shut things down for the night and then nothing the next morning. I'm a software guy and am not as well versed in EE stuff as I like to be, but even my EE partner on the project has no ideas of what caused its death.

Anyway, I do appreciate the efforts people made on my behalf...thanks again.
