MCUXpresso 11.01 doesn't work with J-Link anymore

The last version (11.0) worked without any issues for me but in 11.01, the Segger J-Link support is totally broken.  A message dialog pops up saying ""J-Link support unavailable". Pressing "yes" just let's me the path to "JLinkGDBServerCL.exe" again, but the path is already correct. Pressing "no" causes the debugging to fail:

Error in final launch sequence:

Failed to execute MI command:
source C:\Program Files (x86)\SEGGER\JLink\JLinkGDBServerCL.exe
Error message from debugger back end:
C:\Program Files (x86)\SEGGER\JLink\JLinkGDBServerCL.exe:1: Error in sourced command file:
Undefined command: "MZ".  Try "help".

The GDB server itself works perfectly fine, also Segger's Ozone works like a charm and again, it worked in 11.0 before I installed 11.01.

So after wasting an hour or two re-installing J-Link and MCUXpresso, I downgraded to 11.0 and after some initial struggling, I got J-Link debugging to work again.

Any ideas?
