Admin panel: left side menu not responsive

Very pleased with CWP, coming from cPanel.

But: almost always, the CWP7pro.admin left menu is not responsive to clicking. Only a refresh (F5) of dashboard click (only item that works) will make the menu responsive again.

Sometimes expanded menu's are also collapsed. This behaviour is driving me nuts...

Howto disable or fix it??

Using: AlmaLinux 8 in an lxc container on Proxmox.

What browser are you using to access? Any potentially interfering extensions (ad blocking, cookies, tracker blocking)?
Try a Private/Incognito window and connect to your server. See if you get the same behavior.
