Programming ATTiny3224 with IDE 2.3.4

Development Tools IDE 2.x
1

I have been using IDE 2.3.4 to program my ATTiny3224s. Just recently, it has been failing. See output below. When I use IDE 1.8.19, it works fine. I have tried uninstalling IDE 2.3.4 from my Windows 10 desktop and then re-installing it. Still getting failures. I am using an Adafruit Friend Serial HV UPDI Programmer. Any help would be appreciated.

Sketch uses 2142 bytes (6%) of program storage space. Maximum is 32768 bytes.
Global variables use 294 bytes (9%) of dynamic memory, leaving 2778 bytes for local variables. Maximum is 3072 bytes.

Just one observation which may not be related to the current problem. It appears that your windows account name is forename space lastname. Not all applications react well to path names with embedded spaces.

I have not had problems in the past with my windows account name. The file compiles fine under IDE 2.3.4, just won't program the ATTiny3224. Again, no problems at all with IDE 1.8.19 with compilation and programming.

Like I said, it is not clear it is the problem. I try to avoid it because of reports like this: Spaces in sketch names not allowed anymore in IDE 2.0.4? or Upload fails if path contains a space · Issue #958 · arduino/arduino-cli · GitHub
