It looks like you have the 64 bit Java installed and it updated a 32 bit Java as a result, the 32 bit java is running and blocking the 64 bit from running.
C:\Program Files (x86)\Java are for the 32 bit version you do not want them. You should uninstall the 32 bit version unless it is required for some other app. Since you have the correct path (I believe 251 is the latest version) all should work after that, but I’d reboot before relaunching.
Open command prompt and type java -version and see if the correct version is listed.
If you do need 32 bit Java for some other app then
On a Windows system , edit the initialization file:
a. Open C:\Program Files\Galaxy Watch Studio\GalaxyWatchStudio.ini in a text editor.
b. At the end of the file, add the location of your Java executable file (including the absolute path name). For example, if you installed Java version 1.8.0_251, add:
-vm C:\Program Files\Java\jre1.8.0_251\bin\javaw.exe
c. Save the changes to the file.
Reboot and try to launch GWS again
