What was the last program downloaded?
Is the FS26 hot?
If a low-level pulse can be observed on the reset pin, please use an oscilloscope or logic analyzer to measure the frequency.
Did you follow the 3.2 Plug in the Power Supply method to make the FS26 SBC start with disabled watchdog?

Best Regards,
Robin

Q1. What was the last program downloaded?
Q2. Is the FS26 hot?
Q3. If a low-level pulse can be observed on the reset pin, please use an oscilloscope or logic analyzer to measure the frequency.

Q4. Please tell me which LEDs are light. If you don't tell me the specific information, it will be difficult for me to help you find the root cause quickly.

External debugger or onboard debugger did you select?

Follow the steps 3.3 Connect the Debugger Cable,

Connect a micro-USB cable to the J40 connector to debug via the on-board S32K3 debugger.

The D14 should light up. And then you will see the Port: Embedded Multilink Rev A in PEmicro Debugger configuration view:

I USE ON BOARD THE BUG NAME : Debugger : U-Multilink

AND, WHEN I CONNECTED BY, POWER, USB, AND J12 DUBUGGER PINS

TURN ON TRTPWR IN MY DEBUGGER...

And when I did it for the first time, it was debugging

I can't do it all of a sudden

I changed it to GDBMI FORT NUMBER and SERVER FORT NUMBER

But now it's the same environment you sent me

Please note that some older versions of Multilink do not support S32K3, see the discussion in: s32ds-v3.4 debug s32k344 via PE

Tell me the version of S32K3 RTD you use.
Or send me the project you tested for checking.

Have you tried the onboard debugger (J40) with J12 disconnected?
