Hello Sushanth,
The first thing we will do is take you out of Insider program. Delete the entire WindowsSelfHost Key. It will be rebuilt after a reboot:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost

Download the ISO of 26100.1150 from here:
https://www.microsoft.com/en-us/software-download/windowsinsiderpreviewiso
Mount the image file and run setup.exe within Windows. This is known as a repair install. You will retain all files. As with any major install, ensure you have your important files backed up.
This will put you on 24H2 that will be released shortly. Run Windows Update and this will take you to 26100.1742. There is no need to join Insider for the updates.
If you want to run the Release of 23H2, you will have to do a clean install which means removing everything. Your best option is going to 24H2.
Regards,
