Cant open some apps being on a standard not local account (no admin rights)

[MSCom]

I recenltly watched a tutorial on youtube to have a more secure Computer. Before that I only have one account (not local), which had admin permissions. The video told me its better to create an extra local account with admin permissions, and make my own account which I only will use a standard account. That way I just have to enter the admin password for certain important stuff/apps, and possible viruses/malware on my standard account wont have any admin permissions that easily. Now I wanted to open the app "MysticLight" which controls the RGB Lightning of my RAM, motherboard etc. But unfortuanlty the app just didn't start, as if I didn't clicked it. Even if I tried to run as administrator with my admin password it didnt worked. But when I switched to my new account (admin) which should normally dont be used, the app started normally. This problem accured not only with "MysticLight", several control apps just dont want to launch on my "changed to standard permissions" account
