I did these changes yesterday night based on an AI search and the 
following AI explanation: "During startup, QGIS executes a command line 
script to verify that GRASS is responsive. It scans the resulting text 
output line-by-line looking for the phrase "GRASS GIS " to confirm a 
valid installation. However, modern GRASS releases changed their 
terminal output format and no longer include the word "GIS "—they just 
output "GRASS " followed by the version number. This discrepancy causes 
the unpatched QGIS script to throw a critical error . By deleting the 
word "GIS " (keeping the trailing space after GRASS), the script 
successfully detects the modern GRASS startup string, passes the 
verification check, and allows your profile .ini paths to load the tools 
into your Processing Toolbox ."

The AI also recommended to do the following: Search for the qgis3.ini 
file in the folder C:\Users\User 
Name\AppData\Roaming\QGIS\QGIS3\profiles\<Profile_Name>\QGIS\, open 
qgis3.ini in a text editor, search for the code block starting with 
[Processing], adding the following two lines to force QGIS to look for 
GRASS at the specific path where GRASS is actually placed by QGIS:

Configuration\GRASS8_FOLDER=C:/OSGeo4W/apps/grass/grass84
Configuration\block_grass=false

It seems that modifying grass_utils.py is sufficient, but this might be 
another problem/solution for other users.
