### Microsoft PowerToys version

0.85.1

### Installation method

PowerToys auto-update

### Running as admin

None

### Area(s) with issue?

Mouse Without Borders

### Steps to reproduce

Auto-Update PT with Mouse Without Borders.

I only have 3 modules activated/enabled:
Image Resizer
PowerRename
Mouse Without borders





### ✔️ Expected Behavior

I was expecting that using the Auto-Update feature in PT that my settings would remain the same and I would not have to reconfigure anything once the update was complete - or that there would be a notification as to  what settings are not saved and restored upon updating so that I would know what changes need to be done so that the feature would work.

### ❌ Actual Behavior

After updating both my Windows 11 PCs with the latest PowerToys update, neither computer can see each other.
I tried rebooting both PCs, uninstalling and reinstalling PT from Github, rebooting, and still, neither computer can connect and share the mouse.  I have tried the mouse/keyboard directly connected to both machines (using a USB only KVM) -- still cannot access the other computer's mouse or keyboard functions.
Initially, before the update, I was running both PT on both computers as services (PowerToys.MWB.Service) and after the update via the auto-update function neither computer retained the Service status, so I fully closed PT and restarted it as an Admin. I then set  MWB to run as a service, restrarted both computers again (and one of the two computers is running as a very busy Plex Server, so it is really inconvenient to restart that computer) and they still can't find each other.
I do have the  Original MWB UI also enabled as well as all the Keyboard shortcuts disabled (as I have always done).
I also have the IP Mappings designated for both machines on both computers IP Mappings page.  on occastion I get a message about this settting being used, but it can not locate the other device(s) -- I can't remember the exact popup message.
I will also say that I ran the "Add Firewall rule...." batch on both machines and this did not resolve the issue either.
Any help in solving this issue would be helpful, and I am willing to take any and all suggestions and report back to you the results to help this issue from occuring again in the future.
** I have experienced this or a similar issue with the last (2) auto-updates, but I can't recall how they ended up being resolved since I tried so many (much of the same reported above) different things.
I have a very basic/boring computer setup and since this has happed more than once, I fell confident that others are having the same or similar issue.
Looking at Task Manager (for the first time since this issue) I do see two instances of PowerToys.MouseWithoutBorders running under Details and have created and attached memory dumps from each of them.<!-- Failed to upload "PowerToys.MouseWithoutBorders <!-- Failed to upload "PowerToys.MouseWithoutBorders.zip" -->
** Well, I tried to upload each individual DMP file as well as a 2nd attempt to upload them as one Zip, but they all failed with no explanation as to why (size, file format, etc).

### Other Software

The apps/programs on each of the two computers I use Mouse WIthout Borders on have MINIMAL installed apps, services and driveres.

Both are up to date with all available updates, Windows and otherwise.

- One PC is running Windows 11 Pro Insider Preview Build 27729.rs
- The other is running Windows 11 Pro 24H2 with current feature Experience Pack.

the specific PT MWB version is the same as the main PT version: 0.85.1.0[MWB Mini Log - Last8wide (Windows 11 (24H2).txt](https://github.com/user-attachments/files/17441821/MWB.Mini.Log.-.Last8wide.Windows.11.24H2.txt)
