Hi @MCubedMama

I faced the similar issue when trying to open the PAD, but not at opening the flows, so I'm not sure whether the same steps will work for you also, but below are the steps what I have done

1) Close the PAD, and also exit from the Taskbar as well

2) open This PC and in the address bar type as %localappdata%

3) Once you are there in Local-> Search for Microsoft->Power Automate Desktop. So backup this folder(Power Automate Desktop) to another place and then delete from the Local folder. This will reset the logins and cache everthing

3) Reopen and PAD will ask you to sign- in again and check if you are still getting issues are not

@Srini007 I have the same issue. I have attached a screenshot of my error. This started happening when my Power Automate Desktop was updated to the following version:

Please note I am experiencing this issue after I login and click on 'Create New Flow' or on opening a previously created flow.

I can't recall what the resolution was, but it may have just resolved itself
