MCUXpresso 11.4.0 on Mac Big Sur with J-Link Ultra+ v7.50 not launching debug correctly

I have upgraded to MCUXpresso IDE v11.4.0 [Build 6224] [2021-07-15] which finally fixes the editor issues on Big Sur!

Using the included J-Link version 7.50 does not launch debug correctly (for IMXRT1062).   It just sorta launches quickly and doesn't load flash or execute the program/breakpoints.

I changed the IDE to use the previous J-Link version 6.88c and that still works correctly, so I can use that for now.

Has J-Link 7.50 been confirmed to work with the IMXRT1060 (on Mac)?

OK, Here is the requested logs from JLink 7.50 and 6.88c:

Also two videos of the debug run, on 7.50 it basically does nothing, it says it is debugging, but doesn't actually flash or run the JLink upload.  On 6.88c it shows the J-Link server run the upload and then start debugging.

Thanks for the logs. Here are a few comments:

1. I see that V7.50a is the version you use. However, according to the Release Notes, IDE v11.4.0 comes with v7.50. Where does V7.50a come from?

2. Target reset seems to be performed correctly when using V6.88c

3. Target reset does not seem fine with V7.50a

4. Flash not written when V6.88c is used. I'm wondering what would happen if flash would be programmed with this J-Link version.

5. Flash programming seems to fail when using V7.50a, thus the debugging experience you encountered.

Would it be possible to use the onboard debug probe and report back the results? If problem is specific to J-Link debug solution, we'll need to reproduce it somehow before reporting it to Segger.
