My Quickbooks screen is stuck on reports menu for one of my clients. The left vertical black menu is missing so is the hamburger and the gear menu has only 3 options

I appreciate you sharing the troubleshooting steps you performed to fix the problem, gilesbelfrage-ic. I've got another step to resolve this. 

The most recent operating systems and platforms were taken into consideration when developing and testing QuickBooks Online. The lack of frequent browser updates on older systems can have a negative effect on QBO performance. I recommend using other supported browsers. 

You can visit these articles below to know the QuickBooks supported browsers and performance overview:

Thank you for your reply.

I'm on Chrome version 110 which is the latest

I loaded Safari and Installed Firefox.

There is still the same problem.

Please note alll my Quickbooks clients work except this one which was shared with me 3 days ago.

Why is my newest client the only one that doesn't work?

Thanks for your help. Hope we can resolve.

Let me direct you to the right support to fix the issue, gilesbelfrage-ic.

It looks like this is some kind of strange behavior. We can usually fix the issue by performing the troubleshooting steps like clearing the cache or using another browser. However, since you've already performed them, and yet you're still experiencing the same, can you try accessing your account in a private browser? I've provided the shortcut keys below:

• Press Ctrl + Shift + N (Google Chrome)
• Ctrl + Shift + P (Firefox)
• Control + Option + P (Safari)
• Press Ctrl + Shift + N (Microsoft Edge)

If this doesn't still solve your problem, I would suggest reaching out to our support team so they can double-check why is this happening. Aside from that, they have the tools to pull up your account in a secure environment to see if there are also other users who are facing the same issue. Here's how to reach them:

1. Go to the Help menu on the upper right side.
2. Click Contact Us.
3. Type your concern in the description field, then hit Let's talk.
