CG issue since B 57.1.4

I flew the WorldFlight as member of Team JeeHell A320 with version B57.1.2 without any problems. As I did not make any updates during World Flight, I missed version B57.1.3 After updating to B 57.1.4 the following (fatal) problem occurs and is still present with B57.2.0:
I plan my flights including load as usual with PFPX, send the plan to TOPCAT and apply load and fuel to the A320 from TOPCAT via WideFS. And as usual I insert the values for Flaps/Trim, FlexTemp and V-Speeds in the MCDU as calculated by TOPCAT.
The issue begins with T.O. config test: I now get the (red) Message F/CTL PITCH TRIM/MCDU/CG/DISAGREE, I never had before. Inflight I realized PROG page does not show the OPT and REC MAX FL indication.That might have been caused, as I realized, by the missing ZFW on FUEL PRED page. In the past I never had to write something there manually when having done the fuel data uplink after loading. I now there inserted the ZFW TOPCAT showed for the flight. Now the OPT and REC MAX FL indication is shown on the PROG page, but FUEL PRED page shows a calculated ZFWCG of 25.0 while TOPCAT calculates a ZFW MAC of 31.8%. An issue?
The fatal thing comes at the end when landing: Vapp calculated on PERF page is 138 kts - not unusual compared with the past. But on final, as you can see from the attached picture, this speed is deep in the red area.

But the plane does not go to protection mode, but keeps this too low speed until ending in stall and impact with >1250 ft/min in the lights before the threshold.
Note: Flying with Prepar3Dv4.5 on a Windows 10 system.
Anyone else with this issue since B57.1.4 (or 3)? Perhaps only those using TOPCAT for loading?

have you verified the Data provided by upload from Topcat, on the INIT B page? Sometimes it happen that data get misssed while the upload via FSUIPC. If this is the case, it´s no problem to upload the data again unless they are correct what is immanent for FMGS.

your issue is with simpatcher not working somehow.
In your P3D menu bar, under addons menu, check if you have an entry such as "airfile OK"
if not, you may have an issue with simaptcher not being installed or not being launched by P3D, you will need to check your P3D addons files in
C:\Users\youruser\Documents\Prepar3D v4 Add-ons\jeehell\add-on.xml
and see if the paths are correct

Checked it:
With B57.1.2 in the P3D addons menu I have 2 entrances:
Simpatcher B57.1
Airfile OK
With B57.2.0 both is missing.
The add-on.xml in C:\Users\youruser\Documents\Prepar3D v4 Add-ons\jeehell\ in both cases is the same, the path points to A320FMGS\SimPatch\SimPatcher.dll.
SimPatcher.dll in B57.2.0 is from 5.12.2022 23:01:54 3,92 MB (4.119.040 Bytes).
SimPatcher.dll in B57.1.2 is from 20.10.2022 19:07:28 3,92 MB (4.119.040 Bytes).
.air file (for CFM) is the same in both cases, CLEANcfm56_5B4.air from 14.03.2022 18:32 9,93 KB (10.173 Bytes)
Do you have any idea what went wrong there? Perhaps a clean install needed?

check if you have a simpatch log which is updated in your logs folder

Both make a log, see attachment (files renamed). Flight with B57.1.2 was successful. With B57.2.0 still no entrances of Simpatcher in P3D addons menu.

make sure your antivirus is not blocking somehow, nor your firewalls.

Maybe I got it running now: Exchanged simpatchConfig.ini with the one of B 57.1.2. The one of B 57.2.0 has sleepTime=50000, the one of B 57.1.2 has sleepTime=120000. Now I get
Simpatcher B57.2
Airfile OK
in P3D addons menu. I will make a test flight now.

As I was victim of the same issue from time to time, I made the same change and thought it fixed it. Unfortunately I did experience the "stall problem" again recently. I did verify that simpatcher and airfile OK were both showing up in the Addons menu so I am really not sure what is going on.
For information I am using TOPCAT to load the fuel and weight in the plane (see viewtopic.php?p=284#p284).
