Version 17.1.3 - Parallels Tools Kernel Extensions Broken?

Just updated my Parallels installation to the latest release (17.1.3), and it looks like some of the Parallels Tools Kernel Extensions are broken in the latest release.
I'm running a full suite of macOS guests - ranging from 10.6 through Monterey - and this is what I'm seeing:
* 10.6 - 10.9 - Parallels kexts appear (?) to be okay, at least superficially. Not 100% sure though.
* 10.10 - 10.15 - multiple Parallels kexts are failing to load, with signature-related errors. Result: shared folders non-functional; slow screen updates; sluggish mouse movement; etc.
* Big Sur and Montery - Parellels kexts appear (?) to be okay. Again, not 100% certain though.
What is clear, is that there are issues for 10.10, 10.11, 10.12, 10.13, 10.14, and 10.15.
Is anyone else seeing similar, things after updating to 17.1.3?
 
This is what I'm seeing, when checking the validity of the Parallels kexts, via 'kextstat':

$ sudo bash -c 'for f in /Library/Extensions/prl_*.kext ; do printf "\nChecking kext ${f}:\n" ; kextutil -t "${f}" ; done'

Checking kext/Library/Extensions/prl_eth.kext:
Diagnostics for /Library/Extensions/prl_eth.kext:
Code Signing Failure: code signature is invalid
ERROR: invalid signature for com.parallels.kext.eth, will not load

Checking kext /Library/Extensions/prl_tg.kext:
Diagnostics for /Library/Extensions/prl_tg.kext:
Code Signing Failure: code signature is invalid
ERROR: invalid signature for com.parallels.kext.tg, will not load

Checking kext /Library/Extensions/prl_video.kext:
Diagnostics for /Library/Extensions/prl_video.kext:
Code Signing Failure: code signature is invalid
ERROR: invalid signature for com. parallels.kext.video, will not load
 
FYI, downgrading to Parallels 17.1.2 - and updating Parallels Tools within each macOS VM - has resolved the issues. So if anyone else is dealing with these issues, downgrading appears to provide immediate relief.
Hopefully Parallels' folks will be able to quickly resolve the kext signature issues, and provide a new bug-fix release.

My 10.9 is not OK, same problem.
 
Same for me. Guest OS is running but just like there are no VM tools installed. Mouse is slow, no video resolution other than minimal, etc.
 
There is a workaround for macOS guests: boot into recovery, run terminal and type 'csrutil disable'.
With disabled SIP all required kexts will be loaded.
 
has anyone found out if the usb problem that has been causing trouble since version 17.1 is now solved with 17.4?
 
Hello guys, We have released the Parallels Desktop latest build 17.1.4. We would suggest you upgrade the Parallels Desktop to the latest build and check.
