Can't load sketch once board updated to 1.0.4

Official Hardware UNO Family UNO R4 WiFi
1

I updated my R4 WIFI to the newest version 1.0.4 through the board manager and the IDE would not load a sketch that worked with 1.0.2. I tried a few other sketches that didn't use the qwiic connector and they worked but the 2 that I had the Sparkfun RTC did not. I went back to 1.0.2 and they worked again. Lesson is : Leave well enough alone. I didn't check what new improvements were included in 1.0.4 and was just interested in the having the latest and greatest. I got caught in this trap when I updated the IDE a while back and went back to 1.8 . For someone with limited knowledge and needs it's not worth spending time figuring out why since the sketch does what I want it to with the older version.

Did the sketches for the QWIC connector fail to upload after the update to board version 1.0.4 but any other sketch would upload? Was there an error message?

Yes, I tried the blink and another couple of sketches that used the matrix and they both loaded. The only message was " Exit status 1 Error compiling for board Uno 4 WIFI" Two sketches that used the Qwiic connector and RTC did not load with 1.0.4

The Exit status 1 - is just the indicator that something failed. There should be some other messages that give hints to what that might be.

Note: I typically always configure my system to do verbose output for both compiles and downloading. Settings in File->Preferences.

I just uploaded a sketch using a QWIIC connector. Although probably about as simple as they come. This was a Sparkfun button, and their example Example1_PrintButtonStatus and it loaded fine. But as the previous sketch I ran configured the WIFI board to be setup for HID (previous sketch included HID.h for things like Keyboard or Mouse).
So I had to do a double-click of reset button, actually I did that a couple of times. Then needed to chose the correct COM port.

I also then loaded another example for the Sparkfun LED Stick and that loaded no problem.

Note: for the examples I had to edit them for Wire1 instead of Wire.

Also my board has the updated ESP32 firmware (0.30.0).

I switched on verbose messages and there was nothing extra. I have not updated ESP32 since I have limited need for WIFI. I switched back to 1.0.2 and everything works. No need for further investigation. I'm good. Thanks
