sorry for the late reply,
so i figured out the problem. The actual problem is windows scaling option for screens of larger resolution.
I am attaching the screenshot for your refrence.
My scaling was set to 110% and the start11 seems to only work with setting with multiplier of 25 only(100,125 etc). Thats why i was not able to view my start menu with taskbar enhanced.
for now i am using 100% as scaling but i would really like you guys to fix this problem with custom scaling.
Thanks and regards
