Refresh error. Log shows .NET issues

We have a reports which refresh worked well on PBRS january 2020 version. After the may 2020 update, it stopped to refresh. The log error message says:

|Error Processing Data Model Refresh: SessionId: xx, Status: Error Failed to refresh the model, Exception Microsoft.AnalysisServices.OperationException: Failed to save modifications to the server. Error returned: 'This feature requires installing a newer version of the .NET framework. To use it, you must install at least 'Microsoft .NET Framework 4.5': https://go.microsoft.com/fwlink/?LinkId=528259. The exception was raised by the IDbCommand interface.

We run it on a Windows 2012 Server with .Net 4.8. The report refrehs flawless on the PB Desktop.

Any hint?

Downgrade to january/2020 version solved to us. Beware, the database schema changed. It is not a easy process. Save the original .PBIXs if you need a complete re-install.

Seens to me that this bug is already solved in the new versions of the server, but we will wait until next version to try a new upgrade.

I am getting a simillar error on one of my reports.

Report Server May 2020
Only one report is having the issue
The report previously refreshed without issue on RS May 2020
I made a change to the report and now get this error:
- [0] -1055784932: This feature requires installing a newer version of the .NET framework. To use it, you must install at least 'Microsoft .NET Framework 4.5': https://go.microsoft.com/fwlink/?LinkId=528259. The exception was raised by the IDbCommand interface.
The server has .NET 4.6 installed

I fixed my issue.

I was connecting to a Web data source that was supposed to be a TSV file. However, I forgot the parameter to make the file a TSV. So instead Power BI was converting the HTML page with the data I needed. This refreshed fine in Power BI Desktop but not Server. I fixed my URL parameters to export to TSV and now the report refreshes without the .NET error.
