Freezing with looking bluetooth keyboard after wakeup

Was an EtreCheck report run on that Mac? Get free D/L from maker's web site. This 1

shows more than Mac App store, version. Can be set to gather more information too.

There may be some conflict or unnecessary items in the background; or perhaps the

effect is due to some cleaner software that has run amok? Those can cause problems.

Is there a Beta version of Big Sur involved? ~ Or one of those 'half-baked' last steps of

Catalina; struggle where a newer build had been offered last week. Then 'a fix' days ago?

The EtreCheck tool can help by locating bad actors so they can be removed as well.

Where's the extended report that this tool generates? Among the other items available

to try; including 'last effort' fully all-new installation, from scratch, may you show us?

Without a clear-er look at what has been installed; one never really know. ~ However

to say everything that could be done, has been? More than likely, is an overstatement.

Some mistaken junk from previous install 'may have been reused' from a Time Machine

backup. A fully-new installation could cure issues; unless there's really a hardware cause.

A 'migration' of older system bits from backups can keep problems alive; and Mac, unwell.

Different machine for daily use, and a reduced software set for the one in question, is

one method to see what can be done with the problematic configuration you have.

While I have four working macs here, two portable and two desktop. Few duplicates

and all these most simply work. Most have Time Machine backups, on external USB

drives. I have a few 'new' unused spare drives. And Clones? Are advised to keep good

an installation available that hasn't any contamination from additional debris inside.

While sorting one set of issues at a time; separate macOS can be a Useful sanity break.

So far little detail has been said, about exact things that've actually gone into this mess.

Good luck & happy trails!🌞🎣

You may try & see if start up in Safe mode could help, at least troubleshoot.

Also there's a way to run in Safe mode and update Catalina system again.

Bits and pieces of the last one or two updates to 10.15.7 may fail. Try again.

Good luck & happy trails!🌞|🎣

You could try doing a reset SMC/PMU, followed by a zap pram. Bluetooth keyboards tend to be finicky on start up and especially for troubleshooting, don’t work well at all. I suggest using the cable that might’ve come with your Bluetooth keyboard and plug it in to your MacBook Pro. You should do this while your MacBook Pro is shut down( keyboard thing)
