Solution 1: Turn Off Developer Mode

Step 2: Now, on the left-hand side pane, click ‘For Developers’. There, check the ‘Sideload apps’ option. Click Yes when prompted.

After you have done uninstall, reboot your system. Now try installing the update now.

Step 2: Follow the instruction and, after the procedure is finished, restart PC.
