ZOOMを起動し、ホストとして登録した定期的なミーティングを開始しました。

が、ミーティング画面が開きません。
タスクバーを右クリックすると、ミーティング画面が見えます（他のメンバーや共有資料）

しかし、開くことができません。
また、その画面の右上の×印をクリックしても終了することができません。

「ミーティングを退出」ボタンを押して、他の人をホストにしました。
それから、ZOOMをタスクマネージャーで閉じて、PCを再起動しました。

それでも同じ状態です。
自分がホストではない、他のミーティングでも同様でした。

どのように対応すればよろしいでしょうか？

I have 2 separate accounts: a personal one and an account from my employer; I use Chrome to access the desktop version of Zoom for both accounts. That Employer account goes through Google for logging in to Zoom. BTW, I'm on an old Intel iMac using the latest version of Catalina (10.15.7). Everything was working perfectly with the Employer account until I upgraded Zoom to the latest version, 5.13.0 (13815). Now, while my personal account goes through and opens a Zoom window perfectly, my Employer account will not open the Zoom window. Just to be clear, for my Employer account, I click the Google option on the sign-in page, then enter my employee email address on the Google page that opens up, at which point I'm taken to my Employer account main page (Profile, Meetings, etc.). Since upgrading to 5.13.0, the Zoom Meeting window no longer opens when I try to start a meeting: I click on the "Open Zoom.us" pop-up, but nothing happens - no meeting window! Meanwhile, my personal account opens up just fine from Chrome. I do not want to use the Zoom within browser Chrome window because it's not clear enough for the meetings I hold. So, I'm now left telling people to use my personal Zoom account for business meetings, which is not appropriate within the organization.

There seems to be no place for me to download the previous version of Zoom I had, with which I had no issues.

Not happy!

I run Zoom yoga classes and use an ipad Version OS14.1.   I have recently started using Rode microphones and connect a lightning cable to use the microphones.  The microphones work well but it has reduced the speaker sound when students  talk to me.  I have to sit next to the ipad to hear them (not helpful when teaching yoga as I am about 2 metres away from the screen).   I am trying to bluetooth a speaker and have looked at the Community posts which state I just need to adjust the speaker information next to the speaker Icon.  Using Zoom on my ipad results in no speaker icon.  I attach a screen shot below.  How do I connect to Bluetooth using the iPad zoom screen please?
