Hi! I am desperately looking for any help.. since my Macbook is quite overheating and has battery draining issues since the last OCLP Update.
I tried to install the new Root patches after the update but got the following output:

- Starting Patch Process

- Determining Required Patch set for Darwin 24

Pulling metallib list from MetallibSupportPkg API

No direct match found for 24C101, falling back to closest match

Closest Match: 24C100 (15.2)

metallib already installed (15.2-24C100), skipping

- Verifying whether Root Patching possible

- Patcher is capable of patching

- Mounted Universal-Binaries.dmg

Failed to mount root volume

Subprocess failed.

Command: ['/Library/PrivilegedHelperTools/com.Dortania.OpenCore-legacy-patcher.privileged-helper', '/sbin/mount', '-o', 'nobrowse', '-t', 'apfs', '/dev/disk1s4', '/System/Volumes/Update/mnt1']

Return Code: 75

Standard Output:

mount_apfs: volume could not be mounted: Resource busy

mount: /System/Volumes/Update/mnt1 failed with 75

Standard Error:

None

Failed to mount root volume

- Failed to mount root volume, cannot continue with patching!!!

---------------------------------------------------------------

I already tried to manually mount the root volume by doing "sudo diskutil mountdisk disk1s4" but that only gave me "Volume(s) mounted Success fully" without it actually being mounted when I go have a look in the Disk Utility....

Did anyone maybe have a similar problem and knows what could fix it? Any help is much appreciated! 🙏🏼
